“…The ratios of the peak cross sections of the X 1 Σ + g -B 1 Π u wing to those of the X 1 Σ + g -A 1 Σ + u wing are higher at lower temperatures. As temperature increases, absorption spectra spread out from the peak spectral regions and there emerges near 900 nm a satellite feature arising from the minimum [42] in the X 1 Σ + g -A 1 Σ + u difference potential and the maximum of the transition dipole moment function [43,33]. We also show the bf contributions to the cross sections on each plot.…”

For the lithium dimer we calculate cross sections for absorption of radiation from the vibrational-rotational levels of the ground X 1 Σ + g electronic state to the vibrational levels and continua of the excited A 1 Σ + u and B 1 Π u electronic states. Theoretical and experimental data are used to characterize the molecular properties taking advantage of knowledge recently obtained from photoassociation spectroscopy and ultra-cold atom collision studies. The quantum-mechanical calculations are carried out for temperatures in the range from 1000 to 2000 K and are compared with previous calculations and measurements.

“…The sodium and zinc density ratios in the vapor phase, calculated according to the Raoutt law [6] for T = 840 K are presented in the second column. The third column in Table 1 gives sodium atom densities estimated from fitting the total absorption coefficient at the Naz X-B and X-A bands, according to (12). For a fixed temperature T we changed [Na] in the simulation of the absorption coefficients of the Na2 X-A and X-B bands until they were equal to the measured absorption coefficients in Fig.…”

Abstract.We studied the conditions for the photochemical formation of the NaZn excimer in the excited 22//state using Naz(21//u) + Zn ~ NaZn(22//) + Na reaction. The N a -Z n vapor mixture was prepared in the heat-pipe oven with the well defined column density and temperature. The Na and Zn atom densities in the vapor mixture were controlled by the preparation of the alloy with different mole fraction ratios of the relevant components in the solid phase. The Na densities were determined from the total absorption coefficient at Nag X-B and X-A bands. The cross section for photochemical formation of the NaZn in the 22//state is estimated to be 17.10-16 c m 2 for the laser excitation at 308 rim, measured relative to the cross section of 470.10-16cm 2 for collisional energy transfer Naz(21//u) + Na ~Nai(23//g) + Na published by Mehdizadeh et al.

Rydberg and doubly excited states of Na2 and Li2 have been studied by optical‐optical double resonance (OODR) excitation spectroscopy. In this short review article we summarize the Rydberg states and doubly excited valence states of Li2 and Na2 that have been observed experimentally. We also give experimental evidence for the electronic characteristic differences between these two types of electronic states observed in our experiments.
