✦ Synopsis

High-resolution Lamb dip spectra of OD and Si"C1 have been observed in a molecular beam. The Lamb dips of OD have a width (fwhm) of 1.5 MHz. For Si'5CI broader Lamb dips were seen; from this broadening the radiative lifetime r,=8-10 ns of individual rotational levels of the B *X +, v' =O state was determined. The hyperfine structure of the rotational transitions could be resolved and explained by the hyperfine splitting of the ground state only.

In a molecular-beam laser-induced fIuorescence experiment on SH, the hyperfine and spin-rotation structure in the A++ \_1/z, u = 0 state has been determined. From Iinewidth measurements. a rotationally dependent predissociation is shown to be present. A natural Lifetime of 3.2 k 0.3 ns is obtained f
