Attributing the absence of DA as for DB to the weakly associated transition probability,[44][51][75] the same cannot be said for DX. From Table 17, the DX emission should be of lesser intensity than BX. In this case, the possible explanation could be due to the weak production of state D, either by the ionic pathway[143] or by the harpoon reaction using states Xe(3P).[99] The principal path of XeCl* synthesis is reaction (3) and the relation of the number of states B to that of state D is 0.053. State D emissions are negligible for XeCl spectroscopy. From Table 17, it is likely that state D will de-excite exclusively towards state X.

In practical terms, every author agrees that double collision is the dominant destruction pathway of Xe2Cl when collision is involved, whatever the chlorine donor. Beyond the radiative disexcitation, the Xe2Cl (42) state is destroyed by a double collision with RCl. Therefore, Xe2Cl* emissions are only observed at weak concentrations of RCl.[16][115][172] The values of the rate constants for reactions (24) are given in Table 36.

Rives et al.[17] results leave open to question whether this process is computable, considering its weak rate constant. Lorents[72] provided only an upper limit. Statistically, kX, should not surpass 6.121012 cm3s-1.[63] One other (old) measure,[169] had already provided an erroneous value for kH. For kX, a statistical analysis is very difficult because of the high dispersion of significant absolute values of doubled uncertainties.

Conversely, the XeH+ ion is formed in the mixtures used in lasers. XeH has three known emission lines. They were observed at 190nm,[46] 250nm[47] and 660nm.[48] However, they have never manifested in the laser spectra, which leads to the assumption that XeH is not formed under the experimental conditions.

The more refined analysis of reaction (4) was carried out by Bates et Morgan.[152] who found that the Monte-Carlo method, Flannery's equation and Langevin's theory can give good results only when the pressure is above 1 atm. The proposed "tidal" theory agrees with the experimental measurements of Mezyk et al.[142] which is evident in Figure 10. This is the norm for lasers. The rate of recombination 4 for reaction (4) is of the same order of magnitude as 3.

Other authors have called attention to the absorption phenomena of molecule Xe2Cl at this wavelength.[163] According to Kannari et al., reaction (3) is the principal pathway for synthesis of states B and C.[131] Tsuji et al. Experimentally, the (CA) and (BA) lines overlap,[61] producing a continuum centered at 345nm, often of low amplitude as can be observed in Figure 11. Meanwhile, no concrete result had been discovered as of 2014. placed this continuum at between 312 and 460nm.[52] The weak observed intensities are attributed to the weakness of the probabilities of the transition of the two emissions opposite that of the BX and by the small amounts of states C formed with respect to states B as was previously seen. estimated the proportions of states B and C formed: 38% for state C and 62% state B.[143] The value of the transition probabilities (theoretical value of IBA/IBX = 0.07; experimental value of 0.05),[52] so the contribution of (BA) emission is about 10%. Several authors[7][61][164] claimed that a laser based on the 345nm emission could be developed, especially at pressures of about 10 atmospheres when states B and C are thermalized. Koltz et al. The width of the emission depends on the transition tending to a strongly repulsive state.

Xenon monochloride (XeCl) is an excimer which is used in excimer lasers emitting near ultraviolet light at 308nm. It is most commonly used in medicine.

States B, D and X have symmetry ( = 1/2) while the C state has symmetry ( = 3/2). The state A is itself split into two sub-states, a symmetry , A1/2 and the other symmetry , A3/2. Common characteristics for all halide states of the noble gases includes a group of related excited states B, C and D and a lower group of dissociatively or weakly bound states A and X.

However, under these conditions, the number of states D formed is very low with respect to the number of states B and C. The faster dissociation of [Xe+(2P1/2)Cl]* with respect to that of [Xe+(2P3/2)Cl]* is responsible for this situation. In addition, the rate constants of reaction (3) relative to these two states of xenon are similar. The rate of XeCl(D) formation with respect to XeCl(B, C) is estimated at about 0.0330.006. In laboratory experiments, the number of the Xe+(2P1/2) and Xe+(2P3/2) states are the same.

Three quantities can be compared with theoretical predictions. The Xe-Xe distance is measured at 3.17 and that of Xe-Cl at 3. The isosceles triangle structure of this state was confirmed. The agreement in values is best for the energy at the bottom of the well that was evaluated at 3.15eV. The fundamental vibrational frequencies for XeXe, is x = 123cm-1 and for XeCl, c = 180cm-1. Only an experiment conducted at the solid state[74] can be compared to these theoretical results. The special state studied was the 42 state.

The available information does not support assuming a more efficient rate of synthesis of the exciplex as the excitation of xenon gradually increases. The rate of synthesis also seems very effective from the 7s[3/2] states[72] without there being any known numerical value. HCL is ambiguous. So far, no measurements go beyond the 5d[3/2] state that is roughly of the same energy as the 6p state. An examination of Table 12 shows that the increase in kQ does not appear to increase significantly with the xenon excitation.

The rate of recombination 4 for reaction (4) is of the same order of magnitude as 3. The proposed "tidal" theory agrees with the experimental measurements of Mezyk et al.[142] which is evident in Figure 10. The more refined analysis of reaction (4) was carried out by Bates et Morgan.[152] who found that the Monte-Carlo method, Flannery's equation and Langevin's theory can give good results only when the pressure is above 1 atm. This is the norm for lasers.

This is true even if the absorption phenomena occur on the side of shorter wavelengths and therefore limits the laser action at the red region of the electromagnetic spectrum from light emission. The measured amplification was correct in the solid state.[39] The liquid state[40] seems like an ideal dye laser although implementation seems complex and costly. Presently, the Xe2Cl laser has not been industrially developed. The first XeCl2 laser was developed in 1980.[36][37] This type of laser is likely to be tunable over a wide range of wavelengths (30nm) in the visible spectrum. Solid state experiments with Xe2Cl*[38] suggest that the gaseous state is more suitable for the development of this type of laser.
