TL;DR: Following photodissociation of vinyl fluoride and vinyl bromide at 193 nm, fully resolved vibration-rotational emission spectra of HF and HBr in spectral regions 3050-4900 and 2000-2900 cm−1, respectively, are temporally resolved with a step-scan Fourier transform spectrometer as mentioned in this paper.
Abstract: Following photodissociation of vinyl fluoride (CH2CHF) and vinyl bromide (CH2CHBr) at 193 nm, fully resolved vibration–rotational emission spectra of HF and HBr in spectral regions 3050–4900 and 2000–2900 cm−1, respectively, are temporally resolved with a step–scan Fourier transform spectrometer. With a data acquisition window 0–5 μs suitable for spectra with satisfactory ratio of signal-to-noise, emission from HX (with X = F or Br) up to v=6 is observed. All vibrational levels show bimodal rotational distributions. For CH2CHF, these two components of HF have average rotational energies ∼2 and 23 kJ mol−1 and vibrational energies ∼83 and 78 kJ mol−1, respectively; the values are corrected for small quenching effects. For CH2CHBr, these two components of HBr correspond to average rotational energies ∼4 and 40 kJ mol−1, respectively, and similar vibrational energies ∼68 kJ mol−1. The separate statistical ensemble (SSE) model is suitable for three-center (α, α) elimination of HX because of the loose transiti...

TL;DR: In this article, Fourier transform infrared (FT-IR) spectroscopy has been used to characterise the changes in barley straw when subjected to biological and chemical treatments, and the untreated and treated straws were also analysed by traditional analytical techniques for neutral sugar residues and lignin.
Abstract: Diffuse reflectance Fourier transform infrared (FT-IR) spectroscopy has been used to characterise the changes in barley straw when subjected to biological and chemical treatments. The untreated and treated straws were also analysed by traditional analytical techniques for neutral sugar residues and lignin. A comparison between the spectroscopic data and the chemical analyses showed that FT-IR spectroscopy was a quick and non-destructive analytical technique which could be used to assess the efficacy of treatments applied to annual plants.

TL;DR: In this article, the temporal behavior of the S n ←S 1 absorption of trans-stilbene was measured in solution with a ≈40-fs time resolution, and it was shown that the amplitude of the vibrational coherence signal is semi-quantitatively related to the intensities in the two frequency-domain spectroscopies, the S 1 ←s 0 absorption and the s 1 resonance Raman.
