Vladimir L. Orkin, Victor Khamaganov, Igor Larin
The reactions between OH radicals and hydrogen halides (HCl, HBr, HI) have been studied between 298 K to 460 K by using a discharge flow – electron paramagnetic resonance technique. The rate constants at room temperature were found to be kHCl(298 K) = (7.9

Richard L. Steiner, David B. Newell, Edwin R. Williams
An improved determination of the ratio of power, measured in terms of the Josephson and quantum Hall effects, and also the meter, kilogram, and second, has been completed. The result is expressed as: W 90/W = 1 + (8187) x 10 -9. This is an order of
