Noushaba Nusrat Mafy’s project work for BS honors was on the modification of water structure in absence and presence of urea, which was investigated by near-infrared (NIR) spectroscopy. Both the addition of urea at different concentrations and increase in temperature in the range of 20⁰ to 65⁰C caused characteristic variation of water absorption peaks. Her MS thesis work was related to the investigation of change of water structure or hydrogen bonding of water at different temperatures both in the absence and presence of different amides (i.e. Urea, formamide, N-methylformamide; (NMF), N, N-dimethylformamide; (DMF)) at different concentrations; which was studied by Fourier transform-near-infrared (FT-NIR) and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. Derivative and deconvoluted spectra confirmed the presence of different structural components or clusters in pure water and in aqueous solutions; which were measured by dynamic light scattering (DLS) measurements. Theoretical calculations provided the energetically stable optimized structures of different water-amide complexes and the influence of hydrogen bonded water on the vibrational frequencies of C-N and C=O group of amide.
