Structure Evolution of Organic Compounds in Shale Plays by Spectroscopy (1H & 13C−NMR, XPS, and FTIR) Analysis
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

Amorphous organic matter in geomaterials also known
as kerogen undergoes significant alteration in chemical structure during
thermal maturation which is characterized using a combination of solid−state 1H
& 13C−NMR, X−ray photoelectron spectroscopy (XPS), and Fourier
transform infrared (FTIR) techniques.
