The singlet transitions \(D^{1} \Pi-X^{1} \Sigma\) and \(D^{1} \Pi-A^{1} \Delta\) of the \(\mathrm{YCl}\) molecule have been investigated using LIF methods. The \(D^{\prime} \Pi\) state has been excited from the ground state \(X^{1} \Sigma\) by absorption of the blue \(4579 \AA\) Ar ion laser line.
The radiative lifetimes of C$(A'II,, v'= 0 and 3) were determined by laser-induced fluorescence to be re(0) = 18.5 f 3 and ~(3)=11.4rt:2 cs. In addition, the lifetimes of C2(d311,, u'= 0 and 1) were measured as re =106+15 ns and 105+15 ns, respectiveiy. The error is 30.
Taking advantage of an improved experimental method. a new \({ }^{2} \mathrm{I}_{3 / 2}-^{-2} \mathrm{\Sigma}\left(18145 \mathrm{~cm}^{-1}\right)\) transition of \(\mathrm{NiF}\) has been rotationally analyzed. It gives a quantitative confirmation of the energy-level diagram published recently (C. D
