Abstract

We investigate femtosecond two-dimensional (2D) vibronic spectroscopy of vibrational wave-packet motion in a diatomic molecule. It is shown that the quantum phase acquired during the time evolution in an anharmonic potential leads to phase changes in the 2D spectrum. This is illustrated for the case of a fractional revival which occurs in the dynamics of a vibrational wave packet. The Na2 molecule is taken as a numerical example to illustrate the power of phase-sensitive 2D spectroscopy.
