Polarization Fourier transform infrared spectroscopy

Analytica Chimica Acta, 1990
Abstract Some Fourier transform infrared spectroscopic studies with linearly and circularly polarized radiation are reported. They were all carried out by means of the differential technique, consisting in the comparison of two single-channel spectra of opposite polarization.

Fourier Transform Fluorescence-Encoded Infrared Spectroscopy

The Journal of Physical Chemistry A, 2018
While time-resolved infrared (IR) vibrational spectroscopy provides insight on structural dynamics of solution-phase systems, current techniques are limited to high concentrations. Fluorescence-encoded infrared spectroscopy (FEIR) can be used to encode IR-driven vibrational excitations into excited electronic states that fluoresce, which can be ...

Fourier Transform Infrared Emission Spectroscopy of SeH

Journal of Molecular Spectroscopy, 2000
The infrared vibration-rotation bands of SeH have been measured in the X(2)Pi ground state using a Fourier transform spectrometer. The bands were observed in a microwave discharge of a mixture of H(2) and Se in the presence of He. The rotational structure of the 1-0, 2-1, 3-2 bands of the X(2)Pi(3/2) spin component and the 1-0 band of X(2)Pi(1/2) spin ...

Fourier Transform Infrared Spectroscopy in Cancer Detection

Future Oncology, 2005
The rapid developments in the field of infrared spectroscopy in the past decade have demonstrated a potential for disease diagnosis using noninvasive technologies. Several earlier studies have highlighted the advantage of using infrared spectroscopy both in the near- and mid-infrared regions for diagnostic purposes at clinical levels.

Infrared and Fourier-Transform Infrared Spectroscopy

2006
During the last decade, infrared spectroscopic techniques have entered the field of photosynthesis and they are meanwhile established methods for probing chlorophyll or quinone molecules in their binding sites and for the investigation of molecular processes in the protein upon electron transfer or proton transfer.

Fourier Transform Infrared Emission Spectroscopy of CS

Journal of Molecular Spectroscopy, 1995
The high resolution spectrum of VCl has been observed in emission in the 3000–9400 cm−1 region using a Fourier transform spectrometer. The bands were excited in a high temperature carbon tube furnace from the reaction of vanadium metal vapor and a trace of BCl3 and the spectra were recorded at a resolution of 0.05 cm−1.

Cancer grading by Fourier transform infrared spectroscopy

Biospectroscopy, 1998
Thirty-nine freeze-dried tissue samples from 17 lymphoid tumors (nine malignant non-Hodgkin's lymphomas) were studied by Fourier transform infrared (FTIR) spectroscopy. The absorbance ratio A1121/A1020 increased, along with the emergence of an absorbance pulse at 1121 cm-1, with increasing clinicopathological grade of malignant lymphoma.
