Raman Spectra and Potential Constants for CF3Cl, CF3Br, and CF3I
Raman frequencies have been obtained for gaseous CF3Cl and CF3Br and for liquid CF3I at â40°C. The assignments are in agreement with previous investigations. The spectra have been analyzed using a simplified, sixâconstant potential function of the UreyâBradley type without the assumption of tetrahedral angles around the central carbon atom. In all three cases, it was found possible to reproduce the experimental frequencies to within less than their experimental error.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70934/2/JCPSA6-22-4-714-1.pd
Raman Spectra, Vibrational Assignments, and Force Constants for BH3CO and BD3CO
Raman spectra of BH3CO and BD3CO have been obtained for the liquid state at â80°C, and a complete assignment of the sixteen fundamentals of the two molecules has been made with the help of the TellerâRedlich product rule and a normal coordinate treatment. The calculations were carried out using the FG method of Wilson, ten symmetry force constants being required to produce a fit with a standard deviation of 0.3% from the observed fundamentals. Extension of the calculations to include the isotopic B10 molecules gave results in agreement with the data available.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69997/2/JCPSA6-26-5-1131-1.pd

Raman Spectra of Hydrogen Peroxide in Condensed Phases. I. The Spectra of the Pure Liquid and Its Aqueous Solutions
The Raman spectrum of liquid 99.5% H2O2 has been obtained at 30° and â40°C and compared with the spectrum of 90% D2O2 at â40°C. Three bands not previously reported were observed and their assignment, together with that of the remaining bands, is discussed.Raman spectra were also obtained for aqueous solutions at 30° and â40°C over the complete concentration range. The interpretation is qualitatively in agreement with the results of other work which indicate that the addition of hydrogen peroxide to water results in more extensive hydrogen bonding and an increased degree of order in the solutions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70695/2/JCPSA6-24-1-41-1.pd
Raman Spectrum and Vibrational Assignments of Gaseous Dimethyl Ether
The Raman spectrum of gaseous dimethyl ether has been obtained and that of the liquid reinvestigated. In the lowâfrequency region of the gas spectrum, two bands have been observed which are attributed to overtones of the torsional motions of the methyl groups. The assignment of vibrational frequencies is discussed on the basis of a C2v symmetry in the molecule.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71201/2/JCPSA6-26-1-122-1.pd
Raman Spectroscopy in Liquid Ammonia Solutions. Vibrational Frequencies and Force Constants for Isotopic Species of the Borohydride Ion Having Tetrahedral Symmetry
All fundamentals of the ions 11BH4â, 11BD4â, 10BH4â, and 10BD4â have been observed in the Raman spectra of some alkali metal salts dissolved in liquid NH3 or ND3 at â50°C. A complete assignment of all observed frequencies has been made and force constants have been calculated by the FG method of Wilson.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70986/2/JCPSA6-28-6-1029-1.pd
