“…In-plane and out-of-plane C-H bending vibrations are observed at 1000-1300 cm -1 and 950-800 cm -1 , respectively. [36][37][38] We observed very strong bands at 1498 cm -1 and 1316 cm -1 in the infrared spectra of the Table 3. These bands arise from the coupling between the in-plane C-H bending and ring C-C stretching vibrations.…”

In this study, Zn (II) compound containing 8hydroxyquinoline (L1:8-Hq) and 2-picoline (L2: 2P) ligands was prepared and its elemental analysis was recorded. Infrared spectra of the ligands and the compound were obtained. The structure of the prepared compound was determined approximately based on the spectroscopic and analytical results. The infrared vibration frequencies of the prepared compound were calculated theoretically employing the ab-initio Hartree-Fock (HF) and density functional theory (DFT) methods with 6-311G(dp) basis set. Finally, the vibrational frequency values of the compound obtained both experimentally and theoretically were compared in details. It was observed that all the experimental and theoretical results are in good agreement with the literature.

“…In-plane and out-of-plane C-H bending vibrations are observed at 1000-1300 cm -1 and 950-800 cm -1 , respectively. [31][32][33] Looking at the spectrum, the bands observed at 1284 cm -1 , 1207 cm -1 , 1176 cm -1 and 1119 cm -1 at medium intensity were marked as in-plane bending. These bands were calculated as 1315.5468 cm -1 , 1216.6726 cm -1 , 1197.0028 cm -1 and 1078.4971 cm -1 in HF and 1284.7295 cm -1 , 1191.5421 cm -1 , 1189.9749 cm -1 and 1104.8523 cm -1 in DFT, respectively.…”

In this study, the molecular geometry of 4-Cyanostyrene molecule was optimized by using the Hartree-Fock (HF) and density functional theory (DFT/B3LYP) with 6-311G(d,p) basis set in the ground state. After the optimization, infrared vibration bands of 4-Cyanostyrene molecule were calculated by using the Hartree-Fock (HF) and density functional theory (DFT/B3LYP) with 6-311G(d,p) basis set. The theoretically calculated vibrational frequencies were multiplied by a scalar factor to correlate to experimental results. These theoretically obtained frequencies were compared exactly with the experimental results of 4-Cyanostyrene. All calculated frequencies were discussed. Finally, the correlation graphs of the theoretical and experimental results were obtained. The results were seen to be quite compatible with each other.

“…[ 7 ] Calcite (CaCO 3 ) is an essential constituent of marble, which is a type of metamorphic rock. Some researchers [ 8–22 ] have performed TL emission on metamorphic calcite. Engin and Guven [ 8 ] studied the dosimetric properties and TL parameters of three calcites from different sites in Turkey: stalactite, marble and flowstone.…”

This marble extracted from deposits in Elazığ in Turkey resembles red meat in appearance and is only found in Elazığ. This type of marble has been widely used in the most famous architectural structures and buildings. In this study, the thermoluminescence (TL) properties of a unique marble that originated from Turkey, named Rosso Levanto, were investigated. Two distinct TL peaks were observed at 160°C and around 375°C. Particle size experiments showed that best TL intensity was seen at 200 μm particle size and therefore dose–response, heating rate, cycle of measurement and fading experiments were carried out on powdered samples with a particle size of 200 μm. The findings revealed good linearity in dose–response, observed up to 0.5 kGy. The reproducibility experiment gave good results, but peak intensity decreased by about 40% in first 6 h of storage in a dark room.
