摘要：

Femtosecond coherence-burst signals due to the rotational coherences in the ground vibronic state of gaseous molecules, air, nitrogen, and oxygen, were observed by using the Raman-induced polarization spectroscopy. The frequencies of the induced coherences between the relational levels are obtained from the Fourier spectrum of the coherence-burst signal. Calculations using a theory of coherent beats due to the Raman-induced rotational coherence reproduced well the observed signal and spectrum. (C) 2000 Elsevier Science B.V. All rights reserved.
