The NeICl complexes. Data on some spectroscopic characteristics of the NeI
35 Cl
(X,v X = 0) complexes are given in Table 6.10. The binding energy of the NeI
35 Cl(A,
v A = 10-23) complexes lies in the (45– 41) cm
−1 interval [34], and that of NeI
35 Cl(B,
v B = 2) is 42 cm
−1 ; its VP lifetime is s > 50 ps [118]. The NeI
35 Cl(A,v A = 14) VP
lifetime was found to be large, (3 ± 2) ns [118].
