摘要：

Peak frequencies, integrated intensities and halfwidths of the stretching fundamentals in the i.r. spectrum of isotopically dilute OH groups in crystalline L-ascorbic acid were measured in the temperature range 4-300 K. Weak coupling between OH and O ... O vibrations of each OH ... O system accounts for the dependence of band shapes on hydrogen-bond strength and on temperature. © 1979.
