Book excerpt: Vibrational transfer and electronic quenching in the lower vibrational levels (v'less than or equal 3) of the B3pi(Ou+) state of 79Br2 were investigated using spectrally resolved, temporally resolved laser induced fluorescence techniques. Spectrally resolved emissions from collisionally populated Br2(B) vibrational levels were observed for Br2 and rare gas collision partners. Vibrational transfer was efficient in the non-predissociative vibrational levels and was adequately described by the Montroll-Shuler model for harmonic oscillators. A single fundamental rate coefficient for vibrational transfer from v' = 1 to v'= 0, kv(1,0), characterizes vibrational relaxation. For Br2, the value was kv(1,0) = 3.6 + or - 0.4 x 10 exp-11 cu cm/molec.sec. For rare gas collisions, values ranged from kv(1,0) = 2.5 + or - 0.3 x 10 exp-11 cu cm/molec.sec for helium to kv(1,0) = 3.1 +/- 0.4 x 10 exp-11 cu cm/molec.sec for xenon. Electronic quenching rates for the observed vibrational levels were obtained from the same data. For Br2, the quenching rate coefficient was kq = 3. 7 + or - 1.2 x 10 exp-11 cu cm/molec.sec. Quenching rate coefficients for the rare gases were smaller, kq = 8.0 + or - 1.2 x 10 exp-12 cu cm/molec.sec.

This book was released on 1995 with total page 1154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first stimulated emission pumping (SEP) experiments more than a decade ago, this technique has proven powerful for studying vibrationally excited molecules. SEP is now widely used by increasing numbers of research groups to investigate fundamental problems in spectroscopy, intramolecular dynamics, intermolecular interactions, and even reactions. SEP provides rotationally pre-selected spectra of vibrationally highly excited molecules undergoing large amplitude motions. A unique feature of SEP is the ability to access systematically a wide variety of extreme excitations localized in various parts of a molecule, and to prepare populations in specific, high vibrational levels. SEP has made it possible to ask and answer specific questions about intramolecular vibrational redistribution and the role of vibrational excitation in chemical reactions.

Available in PDF, EPUB and Kindle. Book excerpt: The book reviews the results of vibration-rotational spectroscopy of molecules obtained recently by combining modern computational methods of quantum chemistry with the new techniques of high-resolution rotational and vibration-rotational spectroscopy. It shows for example that the tunneling vibration-rotational spectroscopy of the van der Waals complexes provides a new look at intermolecular forces while the high precision and sensitivity of the submillimeter-wave and Fourier transform microwave spectroscopy make it possible to study complex rotational spectra of molecules in excited vibrational states. New results of high level ab initio quantum chemical computations of vibrational and rotational energy levels and dipole moment functions of unusual molecules will be discussed together with the recent discovery of clustering of energy levels in asymmetric tops. Group theoretical analysis of floppy molecules, especially the tunneling effects in nonrigid molecules, will also be discussed.
