Raman scattering has been used to investigate monohydrated L-asparagine
single crystals for temperatures above 300 K in the spectral region
between 20 and 3500 cm(-1). It is found that several phonon peaks
characterizing the orthorhombic D-2(4) room temperature phase are
notably suppressed in intensity for temperatures higher than similar to
363 K. This is evidence of a new phase in this hydrogen-bonded
crystalline system, and the transition is compared with both the
high-pressure and the low-temperature phase transitions undergone by the
crystal. (c) 2006 Elsevier Ltd. All rights reserved.
