A Note on the Vibrational Frequencies and the Entropy of Decaborane

摘要

The infrared spectra of solid decaborane and of decaborane in a solution of carbon disulfide as well as the Raman spectrum of the solution have been recorded. A rough selection of fundamental frequencies is made; this, together with the molecular parameters from xhyphen;ray data, is used for calculatingS298.160of the gas, for which a value of 83.85 eu is obtained. This figure compares with that derived from thermodynamic measurements, namely, 87.36 eu.
