TLDR
In this paper, the authors investigate whether the vegetation influences H horizon composition and the water-soluble fraction of this horizon, H horizons of three subsequent succession stages (Pinus/Empetrum, Fagus/Vaccinium-Fagus without undergrowth) were sampled, fractionated, and analysed with 13 CPMAS-NMR, pyrolysis-GC/MS, and by pollen analysis.About:

The supramolecular structure of humic substances: A novel understanding of humus chemistry and implications in soil science
TL;DR: A review of the scientific understanding of the molecular structure of humic substances can be found in this paper, where a large body of evidence suggests that the traditional view that humic compounds are polymers in soil is not substantiated by any direct evidence but only assumed on the basis of laboratory experiments with model molecules and unwarranted results by incorrectly applying either analytical procedures or mathematical treatments developed for purified and undisputed biopolymers.

Molecular dynamics of organic matter in a cultivated soil.
TL;DR: In this paper, pyrolysis-GC/MS/C-IRMS was performed on maize plants and on two samples from the same soil that had undergone a vegetation change from the C3 plant wheat to the C4 plant maize.

Soil organic matter chemistry in allophanic soils: a pyrolysis-GC/MS study of a Costa Rican Andosol catena
TL;DR: In this paper, the authors investigated a catena of allophanic and non-allophanic soils in Costa Rica to determine the effect of such binding mechanisms on SOM chemistry, and the results do not support the existing theory of chemical protection of plant-derived components through binding to allophane, iron and aluminium.

Structural Characterization of Soil Organic Matter and Humic Acids in Particle-Size Fractions of an Agricultural Soil
TL;DR: In this article, the chemical structure of bulk soil organic matter (SOM) and its corresponding humic acid (HA) extracts from different aggregate-size fractions ( 250 μm) of a dark brown Mediterranean soil.
