TL;DR: In this article, a Fourier transform infrared isotopic study of the products from the vacuum ultraviolet photolysis of diacetylene and 1,3 butadiene trapped in solid argon has enabled the identification of the 1543.4 cm−1 frequency as a vibration of the C4 molecule.
Abstract: A Fourier transform infrared isotopic study of the products from the vacuum ultraviolet photolysis of diacetylene and 1,3‐butadiene trapped in solid argon has enabled the identification of the 1543.4 cm−1 frequency as a vibration of the C4 molecule. The assignment is confirmed by the observation of the frequencies for seven carbon‐13 substituted isotopomers of the molecule.

TL;DR: A combination of spatial interference patterns and spectral interferometry are used to find the global phase for non-collinear two-dimensional Fourier-transform (2DFT) spectra and cross-linear polarized 2DFT spectra are correctly "phased" using the all-optical technique, where the SRTA is not applicable.
Abstract: A combination of spatial interference patterns and spectral interferometry are used to find the global phase for non-collinear two-dimensional Fourier-transform (2DFT) spectra. Results are compared with those using the spectrally resolved transient absorption (STRA) method to find the global phase when excitation is with co-linear polarization. Additionally cross-linear polarized 2DFT spectra are correctly “phased” using the all-optical technique, where the SRTA is not applicable.

TL;DR: Measurements by Fourier transform spectroscopy of the vacuum wavenumber, line width, and relative signal strength of 928 lines in the Ar I spectrum illustrate the sensitivity of Ar I wavelengths to conditions in the light source.
Abstract: We report precision measurements by Fourier transform spectroscopy of the vacuum wavenumber, line width, and relative signal strength of 928 lines in the Ar I spectrum. Wavelength in air and classification of the transition are supplied for each line. A comparison of our results with other precision measurements illustrates the sensitivity of Ar I wavelengths to conditions in the light source.

TL;DR: In this paper, single-crystalline vanadium oxide nanobelts were obtained through a surfactant-directed growth process under hydrothermal conditions using V2O5 as a precursor.
Abstract: Single-crystalline vanadium oxide nanobelts were obtained through a surfactant-directed growth process under hydrothermal conditions using V2O5 as a precursor. The shape and size were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), ultraviolet/visible (UV/vis) spectroscopy, X-ray photoelecton spectroscopy (XPS), high-resolution TEM (HRTEM), and selected area electron diffraction (SAED) were used to characterize the composition and structure of the as-prepared nanobelts. The as-obtained vanadium oxide nanobelts are up to several hundreds of micrometers in length, 100−200 nm in diameter, and 20−30 nm in thickness. A possible mechanism was proposed to account for the formation of the nanobelts. The influence of the concentration of reactants, the reaction time, the concentration of the surfactant, and the reaction temperature on the morphology of the resulting products are discussed in ...
