About 200 pure water-vapor spectra covering the region from 800 to 3500 cm −1 were recorded with resolution of 0.1 cm −1 at temperatures 311, 318, 325, 339, 352, and 363 K using a 2 m base White cell coupled to the BOMEM DA3.002 FTIR spectrometer. The water-vapor pressure ...
FTIR spectroscopy revealed additional insight into the nature of the mineral-bound water films under study (Fig. 4). In all cases did the micrometer-sized particles exhibit highly comparable distributions of O-H stretching frequencies, namely with an intense band at ~3400 cm−1 and a ...
FTIR spectra, obtained with a PerkinElmer (Waltham, MA, USA) Spectrum One instrument in the range from 650 to 4000 cm-1, were used to characterize the functional groups of the synthesized PU films and also to investigate hydrogen bond- ing in the hard segment. 56 Food Eng Rev (2021) 13...
The SA/PEG1000 hybrid prepared at optimum conditions was subjected to FTIR analysis. The particles size of its emulsion was determined using the TEM. The fabric treated with such hybrid emulsion was investigated using the SEM. 3.3.1 FTIR Spectra of the SA/PEG Hybrid The FTIR spectrum of the...
Fourier Transform Infrared (FTIR) spectroscopy is employed to identify the characteristic absorption bands associated with the silica framework of KCC-1. The FTIR spectrum of KCC-1 typically displays several distinct bands34,35. The broad band around 3400 cm−1 is attributed to the O–H stret...
FTIR spectroscopic measurements of the H2O-D2O fraction The quantitative FTIR spectroscopy of evaporating D2O droplets exposed to ambient air confirms the absorption of H2O. FTIR provides the absorption spectrum of the specimen in the range of infrared wavelengths at which the frequencies of various mol...
Vibrational spectrum of the acetone-water complex: A matrix isolation FTIR and theoretical study The FT-infrared absorption spectrum of the hydrogen-bonded acetone-water complex has been investigated in solid argon matrices. Acetone and water vapors we... XK Zhang,EG Lewars,RE March,... - 《Jou...

A baseline spectrum was recorded prior to introducing pyridine. Subsequently, the catalysts were exposed to pyridine vapor in Ar for 20 min, generated by passing Ar flow through a bubbler filled with liquid pyridine24. Physically adsorbed pyridine was subsequently removed with pure Ar for 50 ...
From a REMPI spectrum of an undeflected water beam, it was confirmed that the supersonic expansion was composed predominantly of the j K a K c = 000 and 101 rotational states of H2O, i.e., the ground states of p- and o-H2O, respectively. A possible minor contribution from the...
