Two‐color resonant four‐wave mixing (TC‐RFWM) is advertised as a unique spectroscopic device, enabling direct time‐resolved measurement of the collisional state‐to‐state transfer characteristics (rates and correlation times). These characteristics are phase‐sensitive and open wider opportunities to study the rotational relaxation processes. Further perspectives are offered by the recently recorded collision‐induced picosecond TC‐RFWM signals of OH. Their quantitative interpretation is now under development.Copyright © 2009 John Wiley & Sons, Ltd.
