Abstract

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.
