In this work, the terahertz (THz) absorption spectra of a typical protein BSA (Bovine Serum Albumin) in aqueous solution were measured under different pH conditions. The temporal changes in the absorption spectra were analyzed using the two-dimensional correlation spectroscopy (2DCOS). By comparing the cross peaks corresponding to the different pH values, it can be obtained that the conformation is...
The aim of present work is to develop an innovative and alternative method for the identification and quantification of methanol in white spirits based on twodimensional (2D) infrared spectroscopy. Firstly, for the identification and quantification of methanol in white spirits, 19 white spirits samples adulterated with different levels of methanol (0.1% to 10%) were prepared. And, the Fourier transform...
In this work, the terahertz (THz) absorption spectra of a typical protein BSA (Bovine Serum Albumin) in aqueous solution were measured under different concentrations. The temporal changes in the absorption spectra were analyzed using the two-dimensional correlation spectroscopy (2DCOS). By comparing the cross peaks corresponding to the concentration changes, it can be obtained that the hydration process...
