摘要：
Best of both worlds! Sensitive cavity-ringdown spectroscopy can be conveniently combined with a pulsed-laser vaporization source. Rotationally resolved spectra of the B(2)Sigma(-) <-- X(2)Sigma(+) transition of AlO showed clearly resolved ground-state levels at least up to V" = 2, allowing spin-rotation doubling to be determined more extensively than in previous studies. In one population of AlO, cooled through supersonic expansion, rotational and vibrational temperatures are estimated at 100 and 1500 K.
