Effect of laser fields on na2 interaction potentials is studied by calculating the time-resolved photoelectron spectrum (TRPES) with the time-dependent wave-packet method. It is shown that the photoelectron spectrum at different delay times reflects the population in different electronic states. We inspect the periodicity of vibrational motion in neutral states, and map the vibrational wave-packet propagation in corresponding internuclear coordinate.

Sixty-five new vibronic levels of the na2 4^3∑g^+ state have been observed in the 33900-35200 cm^-1 energy region above the potential minimum of the ground state by pulsed perturbation facilitated optical-optical double resonance (PFOODR) fluorescence excitation spectroscopy. These new data fill the gap between the low-v levels mainly observed by continuous wave (CW) PFOODR spectroscopy and the high-v levels above the 3s+3d limit observed by pulsed PFOODR with predissociation detection, Molecular constants are fitted below potential shelf around the 3s+3d atomic limit with previously published data (mainly observed by CW PFOODR) and these new data. RKR potential curve has been calculated with the new constants. The constants are: Te= 32127.090 cm^-1,ωe=121.4099(0.20720) cm^-1, Be = 0.116287(0.0002300) cm^-1, Re=3.551 A, An error of the RKR potential curve of J. Chem. Phys. 108, 7707 (1998) is corrected.
