Fourier Transform Infrared spectroscopic investigation of anthracene in the 5-15 THz range

Research output: Contribution to journalArticlepeer-review

Abstract

The room temperature spectrum of anthracene was measured in the intermediate THz range. The anthracene measurements revealed five absorption bands which have not been previously reported. These bands appeared at 4.97 THz, 6.39 THz, 7.65 THz, 11.52 THz and 13.21 THz. There was a good correspondence between the observed experimental bands and the theoretical peaks with the maximum shift of 0.45 THz. The theoretical model discovered that the spectrum of this material in the considered frequency range is comprised of both intermolecular and intramolecular spectral features. Comparison of the spectra of anthracene, BMC biochar and TP18 highlights the availability of tricyclic aromatic compounds in biochar and TP18 soil. This work supplements the existing studies of anthracene in the intermediate THz range. Furthermore, the study hints that not all form of biochar are good fertilizers as some lack the key component attributed to fertility.
