Computational Analysis of Solvent Effects in NMR Spectroscopy.

Solvent modeling became a standard part of first principles computations of molecular properties. However, a universal solvent approach is particularly difficult for the nuclear magnetic resonance (NMR) shielding and spin-spin coupling constants that in part result from collective delocalized properties of the solute and the environment. In this work, bulk and specific solvent effects are discu...

Solvent Effects on the Barrier to Rotation in Carbamates.

In the 40 years since the inception of dynamic NMR methods, much effort has been invested to quantify and understand the barrier to rotation about the C-N bond in amides.1 Carbamates, which also exhibit the approximately planar N-CdO framework responsible for hindered rotation in amides, have received considerably less attention, although they are important biologically as anticonvulsants, loca...

Identification and characterization of pigmented photoreceptor-producing microorganisms using FTIR spectroscopy

The identification, differentiation and classification of microorganisms have been subjects of research for many years. Recently, Fourier transform infrared (FTIR) spectroscopy techniques have gained attention in the characterization and classification of microorganisms based on biochemical profiles and cell structure characteristics. In the present study, the characterization and differentiati...
