Abstract

We show how multichannel nondegenerate four-wave mixing spectroscopy can be applied for fast acquisition of moderate-resolution two-photon resonance spectra of gas-phase samples, specifically, nitric oxide. We present the first results reported for broadband spectra, which can be obtained with a single laser pulse from a number of low-lying vibroelectric states of this molecule, specifically, the A ²Σ(υ = 0), A ²Σ(3), D ²Σ(0), and C² Π(0). The two-photon resonant susceptibility is normalized to the known nonresonant susceptibility of N₂, permitting comparison with previous data obtained by scanning techniques.
