Doppler-free high-resolution spectroscopy is applied to molecular iodine at 532 nm by Nd:YAG lasers. The main hyperfine components as well as the crossover lines are measured for R(56)32-0 and P(54)32-0 transitions by heterodyne beating of two I 2-stabilized lasers. The measured hyperfine splittings including both main and crossover lines are fitted to a four-term Hamiltonian, which includes th...

Semiconductor spintronics is promising, because it allows creating microelectronic elements which are smaller and consume less energy than present charge-based devices. Silicon is the main element of modern charge-based electronics, thus, understanding the peculiarities of spin propagation in silicon is the key for designing novel devices. We investigate the electron momentum and the spin relax...

Stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar X groups; X =OH, SH, H, F, CN, and NO). There are meaningful correlations between changes of geometricalparameters and t...

This thesis focuses on hadronic spin structure at low and intermediate energies, 0 < Q2 < 3 GeV 2. The thesis is divided into two main sections. Each section addresses a different aspect of spin dependent hadronic physics which has not been studied previously in detail. The first section studies hydrogen hyperfine splitting. A polarizability term depending on the proton's G1 and G2 spin depende...

The present study aimed to identify the organizational factors affecting the growth and success of academic spin-offs. The research was conducted based on a mixed method design and the study population consisted of experts of incubation centers and spin-offs. The participants were selected using purposive sampling in the qualitative part and random stratified sampling in the quantitative part. ...
