Notes. Comparison with previous predissociation rate results: E91 (Eidelsberg et al. 1991), L92b (Levelt et al. 1992b), D93 (Drabbels et al. 1993), E94 (Eikema et al. 1994), E06 (Eidelsberg et al. 2006), L92a (Levelt et al. 1992), K95 (Komatsu et al. 1995).

^(a)

Predissociation rates in units of (10¹¹ s^-1);

^(b)

x = J(J+1);

^(c)

held fixed;

^(d)

perturbation results in anomalous line broadening pattern; rate is ~6 for J < 6, 1.8(6) for J = 6, and 3.3 + 0.017 x for J > 6 (see text).
