"Polarized Raman spectra of sigle crystals of lithium formate monohydrate [(LiHCOO.H2O)] have been measured from 4.2 K to 320 K. In the high-frequency region, the observed modes have been assigned and the water molecule vibrations identified. The crytallografic distances between the two oxygens involved in the two bydrogen bonds have been obtained from the frequenciesof the stretching O-H vibrations, and the corresponding [O...O] vibration frequencies have been predicted and identified in the low-frequency region. Although the crystal is thought to the potentially ferroelectric, we have observed no evidence of any structural change or presence of a 'soft' phonon in the presence of the presence of any [LO-TO] splitting or any hydrogen disorder in the crystal".
