Ultrafast 2D-IR spectroscopy is a powerful tool for understanding the and dynamics of biological molecules in solution phase. A number recent studies have begun to explore utility information-rich spectra analytical applications. Here, we report application ultrafast detection classification bacterial spores. Bacillus atrophaeus thuringiensis spores as dry films on CaF2 windows were obtained. T...

X-ray absorption and core-ionization spectra of molecules pumped by two coherent infrared pulses with different polarizations are studied theoretically. We have found a sensitivity the vibrational profile x-ray probe to IR pulses. This polarization dependence is qualitatively for photoelectron spectra. Measurements this allow select difference in Franck-Condon distributions from lowest levels e...

A new application of high-repetition rate, femtosecond Yb-laser/amplifier systems is introduced: transient 2D IR spectroscopy covering the time range from micro- to milliseconds. This approach intertwines measurement spectra with separation an actinic pump pulse and utilizes high repetition rate these lasers in two ways: by offering a resolution (10 µs) enabling many spectra. The well-studied p...

We present first-season infrared (IR) and optical photometry and spectroscopy

The Knoevenagel condensation of aromatic aldehydes with barbituric acid, dimedone and malononitrile occurred in the presence of BF3/nano-γ-Al2O3 at room temperature in ethanol. This catalyst is characterized by powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and energy-disper...

Inspired by ideas from NMR, we have developed Infrared Diffusion-Ordered Spectroscopy (IR-DOSY), which simultaneously characterizes molecular structure and size. We rely on the fact that diffusion coefficient of a molecule is determined its size through Stokes-Einstein relation, achieve sensitivity to creating concentration gradient tracking equilibration in an IR-frequency resolved manner. Ana...
