Abstract
A first infrared pulse at frequency ν1 generates transitions to intermediate states in S0 and a simultaneous visible pulse at ν2 raises the excited molecules to a state in S1. Tuning the frequencies ν1 and ν2 over several hundred wave numbers and holding the sum ν1 + ν2 constant allows the observation of various combination vibrations. The technique is demonstrated on polyatomic molecules consisting of 42 atoms.
