Nondegenerate multichannel four-wave mixing spectraof nitric oxide: two-photon absorption resonance from low-lying excited states.

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(2)Sigma(nu = 0), A(2)Sigma(3), D(2)Sigma(0), and C(2)II(0). The two-photon resonant susceptibility is normalized to the known nonresonant susceptibility of N(2), permitting comparison with previous data obtained by scanning techniques.
