Harteck

Tritium was first prepared in the Cavendish Laboratory by Rutherford, OHphant, and Harteck in 1934 (2,3) by the bombardment of deuterophosphoric acid using fast deuterons. The D—D nuclear reaction produced tritium ( D-H D — -H energy), but also produced some He by a... 

Tritium first detected in atmospheric hydrogen (V. Fairings and P. Harteck) and later shown to be present in rain water (W. F. Libby et al, 1951). 

In spite of the fact that ortho- or parahydrogen, once separated, last for a long time, they are normally not available commercially therefore, they must be prepared as needed. A time-proven process for the enrichment of parahydrogen follows a procedure first described by Bonhoeffer and Harteck [18]. This is based upon the fact that, at low temperature, the energetically more favorable isomer... 

Radiolysis206 of NO has been studied by Mund and Gillerot207, by Harteck and Dondes208,209 and, recently by Hochanadel et a/.101 who used the pulse... 

Decomposition of N02 irradiated by neutrons258 and by fission fragments208 of 235U has been studied by Harteck and Dondes. Reaction intermediates appear...

Cl2 (liq.). The heat of vaporization of liquid chlorine was measured by Estreicher and Schneer,3 Knietsch,1 Pellaton,1 Trautz and Gerwig,1 Johnson and McIntosh,1 Wohl2 and Eucken, Karwat, and Fried.1 See also Harteck.1... 

Harteck and Kopsch68 found that CC14 reacted slightly more rapidly than CH4 with oxygen atoms. The reaction proceeded with a pale red flame to produce CC120 and CI2 in a 1 1 ratio. The overall reaction was... 

The jS bands of NO and the first positive bands of N2 were observed by Reeves, Mannella, and Harteck when mixtures of N and O atoms were passed over sheets of Ni, Co, or Ag.361 Thus, the B2Ylr state of NO and the B2Tlg state of N2 must have been present. The intensity of the bands was much greater than it was in the absence of the metal catalysts. They proposed the reaction... 

Attention was first drawn to reaction (49) by Zeldovich,462 following a suggestion by Semenov, in order to explain the high-temperature oxidation of nitrogen in explosions. Indications of the very rapid rate of this reaction came from the almost simultaneous work of Glick, Klein, and Squire,167 Harteck and Dondes,181 and Kistiakowsky and Volpi.253... 

Harteck and Dondes studied the decomposition of NO by the impact of fission fragments of 235U, and obtained a value of 1.9 x 108 M 1 sec-1 for kig. Kistiakowsky and Volpi used a flow discharge system to react active nitrogen with nitric oxide and studied the products in a mass spectrometer. However, they found the reaction to be too rapid for quantitative measurement and put a lower limit of 4 x 10 M 1 sec 1 on kig. A year later,254 they extended their work and were able to raise the lower limit to 5 x 1010. This result depended on the validity of the stirred-reactor approximation.
