[11] Fourier transform infrared spectroscopy of retinoids

1986
Publisher 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.

Characterization of calcium sulfate grounds and fillings of applied tin-relief brocades by Raman spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy†

, 2010
Applied tin-relief brocade (commonly called applied brocade) refers to a decorative painting technique using tin leaf applied over a supporting relief mass (filling) which is glued to the artwork to simulate gold and silver textile brocades.

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 Infrared Spectroscopy

1992
Typically, 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, 2008
We 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.

Identification of Cobalt Oxides with Raman Scattering and Fourier Transform Infrared Spectroscopy

, 2016
Although Raman spectral fingerprints of Co3O4 have been well established, the infrared spectrum of Co3O4 is less understood due to its dependence on sample morphologies and experimental configurations. The same is true for both Raman and infrared spectra

Infrared Fourier transform spectroscopy of XeH

Molecular Physics, 1988
The 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, 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 ...

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.
