摘要：

Neutron spectroscopy is the only vibrational technique where the intensities can be calculated with reasonable accuracy. This method is applied here to benzene adsorbed in NaY zeolite. The force field of the adsorbed molecule has been refined directly to the observed neutron spectrum so that all the internal vibrational frequencies of benzene can be determined. The external modes of benzene relative to the cations were measured in the frequency range 10-100 cm(-1). This allows the sodium-benzene bond strength to be estimated.
