Assessing the limit of detection of Fourier-transform infrared spectroscopy and immunoassay strips for fentanyl in a real-world setting.

Drug and Alcohol Review, 2019
INTRODUCTION AND AIMS Drug checking is a harm reduction intervention increasingly used in the context of the opioid overdose epidemic. The aim of the study was to determine the limit of detection for fentanyl of two point-of-care drug checking ...

Fourier Transform Infrared Spectroscopy of Peptides

2013
Fourier transform infrared (FTIR) spectroscopy provides data that are widely used for secondary structure characterization of peptides. A wide array of available sampling methods permits structural analysis of peptides in diverse environments such as aqueous solution (including optically turbid media), powders, detergent micelles, and lipid bilayers ...

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 ...

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

2013
Abstract 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, 1987
Abstract 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
