THE $B \rightarrow X$ TRANSITION IN XeI
Radzykewycz, D.; Tellinghuisen, Joel ( 1996 )The $B (1/2 ^{2}P_{3/2}) \rightarrow X (1/2 ^{2}\Sigma^{+}$) transition in XeI (2385-2490\AA) has been recorded at high resolution for the single isotopomer $^{136}Xe_{127}I$, using a Tesla discharge source and a CCD array ... -
THE B STATE OF THE SODIUM TRIMER: PSEUDOROTATION, ROTATION, AND CORIOLIES INTERRACTION
Ernst, Wolfgang E.; Rakowsky, Stefan ( 1994 )Due to a pseudo-Jahn-Teller interaction of a $^{2}E^{\prime}$ and a $^{2}A_{1}^{\prime}$ state, the lowest potential surface of the B state of $Na_{3}$ allows for an almost free pseudorotational motion of the three Na ... -

Hoke, M.; Esplin, Mark P. ( 1990 )Spectral data of samples of carbon dioxide, of natural isotopic abundance, heated to 800 K are being analyzed to yield estimates of band and line strengths. The sample call windows are necessarily at room temperaturel ... -
BAND OSCILLATOR STRENGTHS OF THE $\tilde{C}-\tilde{X}$ AND $\tilde{F}-\tilde{X}$ BANDS OF $H_{2}O$
Yoshino, K.; Esmond, J. R.; Smith, P. L.; Huber, K. P.; Watson, J. K. G.; Ito, K.; Matsui, T. ( 1997 )Several astronomers have recently performed searches using the Hubble Space Telescope for absorption at vacuum ultraviolet wavelengths by $H_{2}O$ in translucent interstellar clouds. Both quantitative interpretation of ... -
BAND SHAPE OF KETONE CARBONYLS IN SOLUTION
Petit, G.; Chapados, C. ( 1990 )In solid solutions of large molecules of biological interest such as chlorophylls and proteins, the infrared spectra show large structureless bands. These characteristics are due to over lapping bands.1 To separate the ... -
BAND SHAPE OF THE $CH_{1}$ STRETCHING BANDS - SOLID POLYETHYLENE.
Grandbois, M.; Trudel, M.; Chapados, C. ( 1991 )The infrared spectra of large molecules of biological interest such as proteins and lipids, show large structureless bands. To separate the components in the massive absorptions, it is necessary to know the band shapes and ... -
BANDS OF $HNO_{2}$
Guilmot, J. M.; Herman, M. ( 1990 )Fourier Transform infrared spectra of $HNO_{2}$ have been recorded with a Bruker IFS 120HR, at an instrumental resolution better than $0.003 cm^{-1}$. The pressure conditions of the various parent gases ($NO_{2}, NO$ and ... -
THE BARRIER TO FREE PSEUDOROTATION IN THE SODIUM TRIMER
Ernst, Wolfgang E.; Vituccio, David T.; Golonzka, Oleg ( 1997 )In the $\tilde{B}$ state of $Na_{3}$, the three sodium nuclei can perform an almost free pseudorotational motion in the molecular plane. The purely vibrational movement is slightly hindered in the lowest vibronic level due ... -
BARRIERS TO METHYL GROUP ROTATION IN THE GROUND AND ELECTRONICALLY EXCITED STATES OF $TOLUENE^{a}$
Borst, David R.; Pratt, D. W. ( 1999 )The high resolution $S_{1}\leftarrow S_{0}$ electronic spectrum of toluene has been recorded. The origin band exhibits two sub-spectra owing to the torsional motion of the attached methyl group. Analysis of these sub-spectra ... -
THE $\bar{A} - \bar{X}$ BAND SYSTEM IN $C_{2}HD$
Auwera, J. Vander; Huet, T. R.; Tansamani, M. A.; Herman, M. ( 1990 )The recent vibrational analysis of the $\bar{A} - \bar{X}$ band system in $C_{2}HD$, performed on the basis of conventional high resolution absorption spectra and of fluorescence excitation jet cooled spectra (1), allows ... -
BASIS SET CONTRACTIONS IN HEAVY ELEMENT EFFECTIVE POTENTIAL CALCULATIONS
Christiansen, P. A. ( 1999 )New relativistic effective potentials have been generated for the sixth-row main group elements and also for key actinide. Basis sets for use with these potentials differ significantly in terms of contraction schemes from ... -
A BEHIND THE SCENES LOOK AT INTRAMOLECULAR VIBRATIONAL ENERGY REDISTRIBUTION
Pate, Brooks H. ( 1999 )The flow of vibrational energy in polyatomic molecules is the fundamental physical process of chemical kinetics. Statistical theories of reaction rates, such as Rice-Ramsperger-Kassel-Marcus (RRKM) theory, assume that the ... -
