Cancer grading by Fourier transform infrared spectroscopy [PDF]
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.

Fourier Transform Infrared Spectroscopy
2013Abstract Fourier transform infrared (FTIR) spectroscopy is a rapid, economical, easy, and non-destructive technique. The IR spectrum of a clay mineral is sensitive to its chemical composition, isomorphous substitution, layer stacking order, or structural modifications.

Infrared Fourier transform spectroscopy of PH
Journal of Molecular Spectroscopy, 1987Abstract The infrared vibration-rotation spectrum of the PH radical was observed in emission using a high-resolution Fourier transform spectrometer. The observation of five bands (1-0, 2-1, 3-2, 4-3, and 5-4) allowed the first six vibrational energy levels of the ground X 3 Σ − state to be characterized. An RKR potential curve for the ground state

[11] Fourier transform infrared spectroscopy of retinoids
1986Publisher Summary This chapter discusses the fourier transform infrared (FTIR) spectroscopy of retinoids, and presents the FTIR spectra of 15 retinoids along with band positions which correlate with the retinoid structures. FTIR spectroscopy offers sufficient instrumental sensitivity, accuracy, and speed of analysis to be the method of choice.

Polarization Fourier transform infrared spectroscopy
Analytica Chimica Acta, 1990Abstract 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 Infrared Spectroscopy
1992Typically, lignins are characterized by IR spectroscopy in the solid state. The examination of lignins in solution has long been a domain of UV and NMR spectroscopy. However, with the advent of the FTIR technique, the IR spectra of liquid samples now can be readily obtained.

In-cylinder Fourier-transform infrared spectroscopy
Measurement Science and Technology, 2008We have adapted a standard Fourier-transform infrared (FTIR) spectrometer (Thermo-Scientific Nexus 670) for in-cylinder measurements of gas spectra. During engine operation, the engine shaft encoder signal is logged continuously along with the FTIR's He–Ne laser signal and infrared interferogram signal.

Infrared Fourier transform spectroscopy of XeH
Molecular Physics, 1988The infrared emission spectrum of the Rydberg molecule XeH was recorded with the Kitt Peak Fourier transform spectrometer. XeH was made in a hollow cathode discharge of 2·2 torr H2 and 0·1 torr Xe. The 0-0 bands of the C 2Π-B 2Σ+ and the D 2Σ+-C 2Π transitions were observed near 3250 cm−1 and 4420 cm−1, respectively.

Fourier Transform Fluorescence-Encoded Infrared Spectroscopy
The Journal of Physical Chemistry A, 2018While 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 ...
