Two-photon vibrational transitions in as probes of variation of the proton-to-electron mass ratio
Vibrational overtones in deeply bound molecules are sensitive probes for
variation of the proton-to-electron mass ratio . In nonpolar molecules,
these overtones may be driven as two-photon transitions. Here, we present
procedures for experiments with , including state-preparation
through photoionization, a two-photon probe, and detection. We calculate
transition dipole moments between all X\,^2\Pi_g vibrational levels and those
of the A\,^2\Pi_u excited electronic state. Using these dipole moments, we
calculate two-photon transition rates and AC-Stark-shift systematics for the
overtones. We estimate other systematic effects and statistical precision.
Two-photon vibrational transitions in provide multiple routes to
improved searches for variation.Comment: 19 pages, 3 figures, supplementary material (v2 fixes an
