Raman Spectral Analysis For Remote Measurement Of Water Temperature

We present a detailed investigation on the temperature-dependence of polarized and unpolarised Raman spectra for various laboratory water, fresh and saltwater samples. We have identified the spectral parameters which are most sensitive to water temperature, and compared these between the water samples from different locations. We have then applied linear regression methods and multiple linear regression methods to investigate the accuracy with which water temperature can be estimated from Raman spectral data.
