Notes. Uncertainties are given in parentheses (1 standard error). Comparison with the previous work E91 (Eidelsberg et al. 1991).

^(a)

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

^(b)

f-value for J′ = 0.

^(c)

f-value for J′ ≥ 0, x = J′(J′ + 1).

^(d)

Each branch are reported with a common averaged J = 0 intercept but being fitted separately, the uncertainties are different.

^(e)

This result includes the unknown band, which may be II ¹Π(0).

^(f)

f gives the f-value integrated from the fit of the entire band including, when required, corrected Hönl-London factors and linewidths.
