A modification of the method of Cusachs and Reynolds has been used to derive valence‐state ionization potentials for the 3 d , 4 s , and 4 p orbitals of third‐row elements. For a fixed ionic charge, these VSIP are found to vary linearly with atomic number.
Various matrix elements of the quadrupole moment of H 2 in the ground electronic state are calculated in the adiabatic approximation and the results are presented in Table II. These matrix elements are of the form < vJ ∣ Q ∣ v′J′ >, where v, J and v′, J′ denote the vibrational and...
The radiolysis of solutions of napthalene and anthracene in cyclohexane and benzene has been studied using 3‐ to 11‐nsec pulses of 3‐MeV electrons. The triplet states of the solutes were observed via their characteristic absorption spectra, while the excited singlet states were observed via...
Time‐integrated spectroscopic intensity measurements have been made on the flame produced by the interaction of a focused ruby laser with powdered solids. Target materials used were Ba(AlO 2 ) 2 , CaS, C, and Al microspheres. Excitation temperatures of 24 000° and 9000°K have been inferred...
The technique of fast‐passage double resonance (ENDOR) is applied to the study of the three conformations of the free radical found when warming single crystals of α‐aminoisobutyric acid, x irradiated at 77°K. The ENDOR measurements, made at 4.2°K, allow the absorption signals for the...
The spin—lattice and spin—spin relaxation times for fluorine nuclei of SF 6 adsorbed to maximum capacity on dehydrated synthetic faujasite have been measured as functions of temperature from 77° to 300°K. These have been interpreted according to the theory of Torrey as arising from...
A new method is described for the numerical solution of g ( x ) = ∫ a b K ( x , t ) f ( t ) d t for f(t) when g(x) is experimental data of limited accuracy. Under these conditions, the well‐known least‐squares and algebraic methods often give poor solutions. The new method is an optimum...
The γ radiolysis of aerated and deaerated, acid solutions of ferrous sulfate has been studied at 20° and applied pressures in the range 0 to 6.34 kbar. Over the entire pressure range, G (Fe +++ )=8.1±0.1 and G (H 2 )=4.1±0.1 in deaerated solutions containing 0.8 N H 2 SO 4 , 1 mM NaCl and 2...
