Abstract
A general technique is presented in which narrow non-Lorentzian laser-induced resonances are used to study molecular reorientation. The experiments, which study the ${\ensuremath{\nu}}_{2}asQ(8, 7)$ N${\mathrm{H}}_{3}$ transition, yield a value of 6 \ifmmode\pm\else\textpm\fi{} 1 MHz/Torr for the excited-state alignment relaxation rate, 50% larger than the corresponding population relaxation rate.
