Lugez, Catherine L.; Lovas, F. J.; Hougen, Jon T.; Ohashi, N. ( 1998 )Spectral data on $K = 0$ and 1 levels of the methanol dimer available from previous and present Fourier transform microwave measurements have been interpreted globally, using a grouptheoretically derived effective Hamiltonian ... 
GLOBAL FIT FOR $CH_{3}OD$ AND THE QUESTION OF INTERPRETATION OF GLOBAL FIT PARAMETERS FOR METHANOL AND ITS ISOTOPOMERS
Walsh, Matthew S.; Xu, LiHong; Lees, R. M. ( 1998 )This talk presents our current progress on global data analysis for the ground vibrational states of methanol and its isotopomers. Global fits of all observed transitions to within assigned experimental accuracies over a ... 
Global Fit of Rotational and TorsionalRotational Transitions in the Ground and First Excited Torsional States of Methanol
Xu, LiHong; Hougen, Jon T. ( 1995 )Methanol data for $\nu_{t} = 0$ (below the barrier) and $\nu_{t} = 1$ (straddling the barrier) have been treated, using a program based on the formalism of Herbst et.al. This program has been rather successful in fitting ... 
GLOBAL FIT OF THE BX SYSTEM OF $Na_{3}$ USING A NEW MODEL HAMILTONIAN
Golonzka, Oleg; Vituccio, David T.; Ernst, Wolfgang E. ( 1996 )The A and X states $Na_{3}$ can be thought of as ordinary asymmetric rotors (complicated slightly by spinrotation interaction) but the B state must be treated as a floppy molecule since it exhibits an almost free ... 
GLOBAL FIT OF TORSIONROTATION TRANSITIONS OF $CD_{3}OH$ TO EXPERIMENTAL PRECISION
Walsh, Matthew S.; Xu, LiHong; Lees, R. M. ( 1997 )The global fitting work reported here for $CD_{3}OH$ is a part of our overall program of global analysis of data in the ground vibration state for methanol and its isotopomers. Our program is aimed, at: (i) achieving a ... 
GLOBAL FIT OF TUNNELING SPLITTINGS IN THE K=0 ATYPE MICROWAVE SPECTRUM OF THE METHANOL DIMER
Ohashi, N.; Hougen, Jon T. ( 1994 )Theoretical results previously developed using an IAMlike multidimensional tunneling formalism are applied to tunneling splitting patterns recently measured at NIST and Kiel University for a type R(J) microwave transitions ... 
GRAIN MANTLE COMPOSITION IN INTERSTELLAR CLOUDS: PROSPECTS FOR INFRARED SPECTROSCOPY
Herbst, E.; Hasegawa, T. I. ( 1992 )In the last decade, IR observations of dense interstellar clouds have been used to detect both gas phase molecules and molecules in the mantles of dust particles. While the gas phase molecules can be studied via high ... 
GREEN BANDS OF CuBr
Hirao, T.; Bernath, P. F. ( 1999 )For a long time it was believed that the lowest lying excited state of the copper monohalides $(CuX, X=F, Cl, Br, I)$ was $^{1}II$. However, resent spectroscopic and theoretical investigations of the electronic transitions ... 
THE GROUND STATE OF THE $B_{3}$ MOLECULE
Hamrick, Y. M.; Van Zee, R. J.; Weltner, W., Jr. ( 1991 )The electron spin resonance spectra of $^{11}{B_{3}}$ in neon, argon, and krypton matrices at 4 K are essentially the same and indicate that the molecule has $D_{3h}$ symmetry and ${a^{2}}A^{}_{1}$ ground state. This is ... 
GROUND STATE OF THE $Nb_{2}^{+}$ MOLECULE
Van Zee, R. J.; Li, S.; Weltner, W., Jr. ( 1993 )Electronspinresonance spectroscopy of an argon matrix at 4K containing laservaporized niobium indicates that $Nb_{2}{^{+}}$ has been trapped and has a $^{2}\Sigma$ ground state. Evidence for this assignment is provided ... 
GROUND STATE OF THE $NbH_{2}$ MOLECULE IN RARE GAS AND DEUTERIUM MATRICES
Van Zee, R. J.; Li, S.; Weltner, W., Jr. ( 1994 )Hyperfine splittings in the electronspinresonance spectra of $^{93}$Nb atoms + $H_{2}/D_{2}$ in argon, krypton, and deuterium matrices 24K indicate that the NbH$2/NbD$2 molecule is being observed. However, the spectra ...

Maria, M. Sanz; Changhong, Xia; Foster, Stephen C.; Saebo, Svein ( 1996 )Ab initio calculation by Searlett and Taylor predicted that Sprotonated OCS is more stable than the Oprotonated isomer. Experimental evidence appears to contradict this finding. Nakanaga and Amano observed a band of ...
