The thermal expansion of fullerite C60 doped with a 4He impurity at T ∼2 K has been investigated by the method of low temperature precision dilatometry in the interval T = 2.2−24 K. The character and the derived values of the thermal expansion co

The lattice parameters of monoclinic ortho-bromobenzophenone (2-BrBP) were determined using powder X-ray diffraction, in the temperature range of 90–300 K. It is found that ortho-bromobenzophenone has small linear expansion coefficients (about 10

Thermal conductivity κ of a single crystal triclinic 4-bromobenzophenone polymorph was measured along axis b from 4.5 to 303 K. The κ values versus temperature were represented as a sum of κ 1 , which generally describes the thermal conductivity o

The heat capacity $C(T)$ of a 2-bromobenzophenone (2-BrBP) single crystal measured at temperatures from 0.4 to 30 K demonstrates anomalies inherent in disordered solids: Instead of the Debye law ${C}_{\mathrm{D}}\ensuremath{\propto}{T}^{3}, C(T)$ sho

Luminescence and other properties of solid 2-bromobenzophenone demonstrate features, which require special attention. We present results, which include DFT calculations, integrated and time-resolved phosphorescence spectra, and excitation spectra. Th

Integrated phosphorescence spectra of meta-bromobenzophenone crystals were measured in the temperature range from 1.6 to 297 K. The spectra were found to contain two series of monomeric bands associated with the stretching mode of the C=O carbonyl at

Integrated and time resolved phosphorescence spectra of the monoclinic (M-form) and triclinic (T-form) polymorphs of 4-bromobenzophenone are measured at temperatures of 293, 77, and 1.6 K. The parameters of the damping kinetics of the most important

Phosphorescence spectra of two 4-bromobenzophenone polymorphs have been measured at 1.6 K. Based on the actual structure data for the triclinic and monoclinic polymorphs, the relevant exciton dispersion laws have been calculated within a 1D model to

Microsecond-level time-resolved photoluminescence spectra of 2-bromobenzophenone are measured on crystalline (at 1.6, 52, and 300K) and glassy (at 1.6 and 95K) samples. For each of these physical situations the characteristic decay times are determin

Phosphorescence spectra of 2-bromobenzophenone (2Br-BP) crystals were measured from 70 K to room temperature. A capital crossover in the emission mechanism takes place within this temperature range, leaving at room temperature only a broad two-hump f
