This work investigates the high-temperature vibrational relaxation and decomposition of nitric oxide (NO) diluted in nitrogen (N2) to target NO–N2 rates relevant air, thereby building off argon (Ar) experiments investigated Part I. [J. W. Streicher et al., “High-temperature shock-heated oxide. Argon dilution from 2200 8700 K,” Phys. Fluids 34, 116122 (2022)] Again, two continuous-wave ultraviol...

The trml mutation of Saccharomyces cerevisiae is a single nuclear mutation that affects a specific base modification of both cytoplasmic and mitochondrial tRNA. Transfer RNA isolated from trml cells lacks the modified base N2,N2-dimethylguanosine, and extracts from these cells do not have detectable N2,NZdimethylguanosine-specific tRNA methyltransferase activity. As part of our efforts to deter...

Molecular dynamic simulation program has been developed which can be used to model the static and dynamic properties of molecular nitrogen (N2) under high pressure. The dynamics of the N2 molecules accounts precisely both translational and rotational degrees of freedom. The rotational motion of the N2 molecule is approximated assuming constant moment of inertia of the nitrogen molecule. The pro...

M(N2)n(+) (M = Y, La, Ce; n = 7-8) complexes have been studied by infrared photodissociation (IRPD) spectroscopy and density functional theory (DFT) calculations. The experimental results indicate that the N-N stretching vibrational frequencies are red-shifted from the gas-phase N2 value. The π back-donation is found to be a main contributor in these systems. IRPD spectra and DFT calculations r...
