TL;DR: In this article, the LiZn excimer formed in the photochemical reaction of Li2(C 1 Πu) with Zn(4 1 S 0 ) was investigated.
Abstract: We performed a study of the LiZn excimer formed in the photochemical reaction of Li2(C 1Πu) with Zn(4 1S0). The Li2(C 1Πu) molecules were prepared by excitation with either a dye laser in the region from 348 to 377 nm or an excimer laser at 308 nm. We observed bound–free emission of LiZn at 477 nm. Nonrelativistic ab initio calculations of the potential energy curves and the relevant dipole transition moments have been performed. Using these results in spectral simulations the observed emission is interpreted as belonging to the 2 2Π–X 2Σ+ transition of the LiZn molecule.

TL;DR: In this article, the authors carried out parallel studies of the quenching process in Na(3p)+H2 collisions and the possible reactive process in N 3p + H 2 collisions.
Abstract: We have carried out parallel studies of the quenching process in Na(3p)+H2 collisions and the possible reactive process in Na(3p)+H2 (v
″=1,2,3) collisions. Rich CARS spectra which were obtained at H2 pressure of 100 mbar and oven temperature of 600 K indicate the presence of vibrationally excited H2 and photochemically produced NaH molecules. Temporal resolution of NaH CARS lines was employed in order to rule out competing collisional processes. We make use of resonantly enhanced CARS methods which enabled us to achieve very high sensitivity for NaH detection.

TL;DR: In this article, Bound-free emission of LiCd molecules is observed in the region from 460 to 500 nm, which shows, in contrast to similar systems, a structured continuum with two distinct maxima at 482 and 489 nm.

TL;DR: In this paper, the authors have observed an enhancement of the P and R lines from X 1Σ+−A 1 Σ+ transitions in the NaH molecules through coherent anti-Stokes Raman scattering (CARS).

TL;DR: In this article, the shape of the emission spectrum was used to obtain information about the population distribution within rovibration levels of the upper state of the bound-free transition.

state, we have calculated the corresponding spectral shapes. The results show that the shape of the emission spectrum can be used to obtain information about the population distribution within rovibration levels of the upper state. Comparison with several experiments is presented.

TL;DR: In this paper, the Coherent anti-Stokes Raman Spectroscopy (CARS) technique was applied to measure the O Q, and S branches from the first, second and third overtones of the XICt ground state of NaH.
Abstract: The Coherent anti-Stokes Raman Spectroscopy (CARS) technique was applied t o measure the O Q, and S branches from the first, second and third overtones of the XICt ground state of NaH. Moreover, P and R doublets were also measured when the anti-Stokes signal was rcsonant with some lines of the electronic transition AIC+XIC+ of NaH. The high sensitivity resulting from pump laser resonances allowed us to study the Na(nl)+H2 -i NaH+H reaction dynarnics.
