Organic matter present in lignite samples collected from different depths (i.e. top, mid and bottom) of lignite source, Ilgın, Konya province, was examined by using subtractive-FTIR-ATR spectroscopy. FTIR spectra were recorded on (i) original samples, (ii) the samples dried at 105°C and (iii) the samples acid-treated and dried. After a combustion process performed for each sample at 650°C for 15min,...
The IR spectra of 5-chloro-10-oxa-3-thia-tricyclo[5.2.1.0 1,5 ]dec-8-ene-3,3-dioxide (COTDO) has been recorded in the region 4000–525cm −1 . The optimized molecular geometry, frequency and intensity of the vibrational bands of COTDO in the ground state has been calculated using the Hartree-Fock and density functional using Becke's three-parameter hybrid method with the Lee, Yang, and...
