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.
