Recent research achievements
By means of two-dimensional
correlation spectroscopy (2DCOS), principal component analysis (PCA) and
multivariate curve resolution (MCR) it was shown, that NIR spectra of water and aqueous solutions of proteins
comprise essential information on the structure of water and protein folding/unfolding phenomenon.
Molar vibrational polarizations for neat liquids and hydrogen bonded systems were determined for the first time.
Evidence was found that in alcohol/water mixtures water-water and alcohol-alcohol interactions dominate.
