TL;DR: In this paper, the authors present the relevant instrumental and theoretical background of polymer deformation and relaxation studies by simultaneous FTIR spectroscopic and mechanical measurements and summarize selected experimental results obtained by this technique.
Abstract: The advantages of Fourier-Transform infrared (FTIR) spectroscopy over conventional dispersive instrumentation have revitalized the utilization of vibrational spectroscopy in polymer research. In the field of rheo-optics primarily the rapid-scanning capability of the FTIR technique has contributed to a more detailed insight into the technologically important process of polymer deformation. It is the purpose of this review to present the relevant instrumental and theoretical background of polymer deformation and relaxation studies by simultaneous FTIR spectroscopic and mechanical measurements and to summarize selected experimental results obtained by this technique.

TL;DR: In this paper, the ν3 band of UF6 was studied at a low rotational and vibrational temperature using a tunable diode laser, and the absorption lines from P(21) to R(27) were measured with a Doppler limit resolution.
Abstract: The ν3 band of UF6 is studied at a low rotational and vibrational temperature using a tunable diode laser. Infrared absorption in a pulsed supersonic free jet of UF6 is observed by phase sensitive detection synchronized with the pulse frequency. Absorption lines from P(21) to R(27) are measured for 238UF6 with a Doppler limit resolution. Only Q-branch peaks are observed for 235UF6 using naturally abundant isotopic species. Isotope shift for the ν3 band is determined to be 0.6040 cm-1.

TL;DR: In this article, the authors present an overview of the determination of the reorientational and vibrational correlation functions from infrared and Raman spectroscopic band profiles, focusing on the objectives of such measurements, on the experimental and computational difficulties and on the possible shortcomings of the rather well-established methodology.
Abstract: The object of this chapter is to present an overview of the determination of the reorientational and vibrational correlation functions from infrared and Raman spectroscopic band profiles. I shall concentrate on the objectives of such measurements, on the experimental and computational difficulties and on the possible shortcomings of ‘the rather well-established’ [1–4] methodology.
