PHOTOPHYSICAL BEHAVIOUR OF SOME MOLECULAR SYSTEMS AND A PROTEIN IN DEEP EUTECTIC SOLVENTS

Abstract

This chapter begins with an introduction on DESs, highlighting their types, physicochemical propertiesandapplications in differentfields. Following this, a brief description of various photophysical studies, such as solvation dynamics, rotational diffusion dynamics and translational diffusion dynamics exploiting the fluorescence behavior of suitable molecular systems, carried out for the work presented in this thesis, are provided. In the later part of the chapter, introductory remarks on the structures and dynamics of protein molecules are presented. This is followed by a description of how their structural stability and conformational dynamics are studied using fluorescence spectroscopy. The chapter is concluded by describing the motivation behind the work presented in this thesis
