Abstract

It is shown that with counter-propagating laser beams of identical circular polarisation, symmetry-preserving transitions in icosahedral molecules produce totally Doppler-free lines in two-photon and four-photon absorption spectra. In the four-photon case, this feature cannot occur for molecules of any other symmetry, and therefore characterises an icosahedral species.
