In some embodiments, distances associated with a surface may be calculated using time-of-flight (ToF) of a plurality of pulses of light occurring at a predetermined frequency. Reflected light from a light emitter may be captured by two or more light sensors. At least one light sensor may be...
Radiative lifetimes of N 2 + (A 2 Π u ) have been determined for vibrational levels v′=1−8. They decrease monotonically from 13.9± 1.0 μ sec for ν′=1 to 7.3 ± 0.5 μ sec for v′=8. A time‐of‐flight method was used to overcome collisional and diffusi...
Atomic and Molecular Calculations with the Pseudopotential Method. III. The Theory of Li2, Na2, K2, LiH, NaH, and KH The pseudopotential theory of diatomic molecules developed in the first part of this series is applied to the calculation of molecular constants for Li2, N... L Szasz,G Mc...
Daily Pacing Allocation doesn't affect the lifetime pacing algorithm's daily budget calculations. Rather, it affects the outcome of flight spend by pacing daily budgets' spend behavior. By selecting Evenly, your line item paces to a geo spend curve that represents available impressions for the ta...
This is a report on the first setup of a recently developed, extremely sensitive and very fast 3D quadrupole ion trap mass spectrometer inline in a metalorganic vapour phase epitaxy (MOVPE) system. This setup was developed ultimately for the decomposition- and the interaction analysis of various ...
The samples were analysed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF MS) during the course of the secretion. Some differences were observed between specimens in terms of relative peak intensities and number of Pvfp variants. In most cases, a higher ...
Lifetime of the c^{3} Π_ {u} Metastable State of H_ {2}, D_ {2}, and HD The lifetime of the v=0 c Πmetastable state of H, D, and HD has been measured using the time-of-flight technique. The velocity distribution of a thermal beam of metastable molecules is sampled and ...
Atmospheric model calculations have shown that short-wavelength UV photolysis is the predominant atmospheric loss process for CBrF3. It was also shown that the 190–230 nm wavelength range accounts for the vast majority of photolysis. The global lifetime of CBrF3 was calculated to be 74.6 years ...
reaction intermediates binding at the interface on the efficiency. Although great progress has been made in understanding the underlying surface chemistry, the reaction sequence remains incomplete, partly due to the lack of direct experimental evidence for unraveling the fast dynamics of CO2•−during...
Being the lightest, most mobile atom that exists, hydrogen plays an important role in the chemistry of hydrocarbons, proteins and peptides and most biomolecules. Hydrogen can undergo transfer, exchange and migration processes, having considerable impact
