The memory of Kent R. Wilson, one of whose many infectious zeals was the preparation, interrogation, and control
of molecular coherences.
Z .The time-gated frequency-resolved detection of coherent anti-Stokes Raman scattering TGFCARS induced by femtosec-
ond pulses allows the imaging of molecular coherences as a polarization interferogram in the time-frequency plane. We
illustrate this for the rovibronic coherence of molecular iodine in the gas phase. q 2000 Published by Elsevier Science B.V.
1. Introduction
The preparation, interrogation, and control of
molecular coherences are central visions of ultrafast
spectroscopies 1
