Pyrene and Biochar (Raman Spectroscopy)

Abstract

Pyrene is a polycyclic aromatic hydrocarbon (PAH) organic compound. Here we consider its Raman spectroscopy, and how it is revealing, when used to create nanograins (Gavilan et al., 2022), a spectrum which is like that we can observe when biochar is investigated. Besides the approach by Gavilan and coworkers, the research by Smith et al., 2016, based on the Raman spectra of several PAH compounds, and proposed to determine an assignment for the bands of char, will be considered too.
