Fourier-transformed infrared photoacoustic spectroscopy of polystyrene film
TLDR
Fourier transformed photoacoustic IR spectroscopy of a solid is demonstrated for the first time in this paper, where an uncorrected spectrum of polystyrene film is shown to be fairly readily obtained, although multiple interferometer-scan averaging is required.About:

Fourier Transform Infrared Spectrometry
TL;DR: The theory and instrumentation for Fourier transform infrared spectrometry are discussed, and important areas of chemistry include atmospheric monitoring, surface chemistry, and on-line identification of chromatographically separated materials.
Journal ArticleDOI
Applications of photoacoustic sensing techniques
TL;DR: In this article, the theory and applications of photo-acoustic (also called optoacoustic) methods belonging to the more general area of photothermal measurement techniques are reviewed, covering excitation of gaseous or condensed samples with modulated continuous light beams or pulsed light beams.

Junhui Shi,Tsz Wai Wong,Tsz Wai Wong,Tsz Wai Wong,Yun He,Yun He,Lei Li,Ruiying Zhang,C. S. Yung,Jeeseong Hwang,Konstantin Maslov,Lihong V. Wang +11 more
TL;DR: This work proposes a method that employs photoacoustic detection highly localized with a pulsed ultraviolet laser on the basis of the Grüneisen relaxation effect that allows water-background suppressed mid-infrared (MIR) imaging of lipids and proteins at ultraviolet resolution, at least an order of magnitude finer than the MIR diffraction limits.

The photoacoustic determination of fluorescence yields of dye solutions
Mark G. Rockley,Kristy M. Waugh +1 more
TL;DR: In this paper, a new method for the measurement of the primary fluorescence quantum yield of dye solutions is presented, relying of the S n → S 1 transition probability as an internal standard for comparison with the S 1 radiationless transition probability, both probabilities being measured by photoacoustic spectroscopy.

Simple, new technique for measurement of fluorescence quantum yields: Application to benzene vapor
TL;DR: In this paper, a new technique was presented for measuring fluorescence quantum yields without recourse to comparison with “standards”, and the first experiments involved a study of benzene in the vapor phase.
