Red sandalwood contains Cd, Fe, Ni, Mn, C, S, H elements. ICP-MS results indicate that the red sandalwood contains Ni (61.877), Cu (281.256), Ba (3722.064) and Sr (6365.482) ppm elements respectively. It has partial semi conducting nature. EPR spectrum of the sample is due to Fe(III) in tetragonal distortion and its ash sample also contains Mn(II) in addition to Fe(III). The g values obtained for Fe(III) in the sample are 6.52, 2.63 and 1.92 respectively. The observed g and A values for Mn (II) are 1.990 and 88.5 G respectively. Mn(II) may be low in concentration in the sample. Optical absorption spectrum clearly indicates the presence of both ferric iron and Ni(II) in octahedral geometry. NIR Spectrum is due to carbonate overtones and harmonics and water fundamentals.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
