摘要：

Cavity ring-down spectroscopy of HNO in the range 17 540-17 590 cm(-1) reveals that lifetime broadening contributes to the linewidths of the (A) over tilde(1)A ''-(X) over tilde(1)A' (110)-(000) K' = 4-K '' = 3 subband rotational transitions. The deconvoluted predissociation-induced widths for the rotational levels of the upper state depend on the value of J', with the deduced lifetimes decreasing from 310 +/- 160 to 40 +/- 6 ps for J' = 4-16.
