Abstract

The exact phase nature of the quasi-liquid layer (QLL) of ice is the subject of interest because it affects both the nature and behavior of the ice surface and the partitioning behavior of dissolved solutes, including those of interest to climate scientists. Here we seek to develop a nondestructive spectroscopic probe of the QLL based on Raman scattering. A survey of possible molecular QLL probes was done in order identify molecules capable of probing the QLL. Results of this survey are presented. We also began construction of a modular Raman spectrometer that has an adjustable angle and phase of incoming light. We hope to use this spectrometer to probe the QLL on ice samples.
