Nitrogen-containing volatiles, molecular structures

The experiments reported here involve measurements of the 1h NMR during pyrolysis of shale specimens contained in open tubes and flushed with dry nitrogen gas so that volatile pyrolysis products are quickly removed, A number of different parameters extracted from the data are investigated for their usefulness in monitoring changes that occur in the properties of the specimen. These parameters relate to the loss of hydrogen from the specimen and changes that occur in the molecular structure and mobility as a consequence of chemical and physical transformations.
