The pyrolysis of nickelocene has been investigated over a wide temperature range (300°–1400°K), at low pressures (∼ 10 −3 –10 −4 torr), and short contact times (∼ 1 msec) in a quartz reactor coupled directly to the ionization source of a mass spectrometer. The cyclopentadienyl and...
The paper contains the results of measurements of the viscosity of six binary mixtures: CO 2 � Kr ; H 2 � N 2 ; He � O 2 ; CH 4 � CO 2 ; CH 4 � C 4 H 10 ; H 2 � He . Measurements were made in an oscillating‐disk viscometer at 20° and 30°C and at pressures from 1–25 atm,...
Vibrational excitation by electron impact, in the kinetic‐energy range 30–60 eV, has been studied for water vapor and carbon dioxide. Intensities relative to elastic scattering have been determined at scattering angles to 15°. Fundamental vibrations are excited with much greater intensity...
Spin–lattice relaxation times have been measured for the protons in gaseous NH 3 and for the fluorine nuclei in gaseous BF 3 as a function of temperature and pressure in the dilute gas region. The measured temperature dependences are as predicted for relaxation resulting from a spin–rotation...
Explicit formulas for derivatives of all orders for matrix elements between HG functions, with respect to the parameters involved, are given. One‐ and two‐electron operators, including nuclear‐attraction and electron‐repulsion energy operators, are considered. The derivatives can be...
X‐ray irradiation of zinc acetate single crystals at 77°K with subsequent examination at 133°K reveals initially an intense EPR signal due to methyl radicals. Decay of the methyl radicals is accompanied by a corresponding increase in another species shown to be the ⋅CH 2 CO 2 − radical....
The infrared spectra of monomeric 7 Li hexafluoroacetylacetonate–tetramethylethylenediamine adduct and its 6 Li analog have been obtained from 4000–90 cm −1 in benzene solution. Normal‐coordinate analysis has been carried out to estimate the Li☒O stretching force constant as well as to...
Atomic Cu, Ag, Cd, and Fe are produced by bombarding the appropriate metal with positive ions from a microwave discharge. The process is similar to sputtering. The metal atoms are trapped in an inert‐gas matrix on a cold window and their uv spectra observed. This is a new method for isolating...
