FTIR spectroscopy and FTIR microscopy of vacuum-evaporated polyimide thin films
Vibrational Spectroscopy, 1999Abstract Polyimide (PI) thin films can be formed by vapor co-deposition of the precursor molecules pyromellitic dianhydride (PMDA) and 4,4′-oxydianiline (ODA) if the resulting polyamic acid film is heated above 150°C. The effects of dose stoichiometry and curing temperature on the imidization rate and crystallization of PI films were investigated ...

In this chapter, several analytical techniques to make the best use of the ‘ordinate scale’ of absorbance spectra are described. The techniques are on a concept of the multivariate analysis, which is usually called chemometrics. To employ chemometrics for spectral data analysis, the accuracy of the abscissa axis must be highly rigid.

Infrared spectroscopy has proved to be a powerful tool for the study of biological molecules and the application of this technique to biological problems is continually expanding, particularly with the advent of increasingly sophisticated sampling techniques associated with Fourier transform infrared spectroscopy in recent decades.

Structural Characterization of Membrane Proteins and Peptides by FTIR and ATR-FTIR Spectroscopy
2012Fourier transform infrared (FTIR) spectroscopy is widely used in structural characterization of proteins or peptides. While the method does not have the capability of providing the precise, atomic-resolution molecular structure, it is exquisitely sensitive to conformational changes occurring in proteins upon functional transitions or upon ...

FTIR analysis of carbonate precursors in manganite coprecipitation synthesis by FTIR spectroscopy
2021The simple perovskite oxides, manganites, are nowadays subject of extensive research because of their electrical, magnetic and photocatalytic properties. Manganites described with general formula A1-xSrxMnO3 (A = Ca, Ba, La) were prepared by the coprecipitation method.
