The identification is ironclad because of the previous IR detection of NCO-, the presence of well-resolved nitrogen quadrupole hyperfine structure, and the observation of nine harmonically related transitions in the millimeter band. B and D are three orders of magnitude more accurate than those derived from the earlier IR measurements, and the theor.
The entire rotational spectrum can now be calcd. NCO- is an excellent candidate for radio astronomical detection because of its high stability, polarity, and favorable partition function.

American Physical Society. We have developed an approach based on first principles to study the process of radiative electron attachment REA to linear mols. The approach is based on accurate ab initio calcns. The electronic continuum states are obtained with the complex-Kohn variational method.
The benchmark calcn. Moreover, our results are shown to agree well with microscopic reversibility applied on a recent photodetachment expt. Finally, the study confirms a previous assessment that the CN- ion is unlikely be formed by REA in the interstellar medium. Within this approxn. A Formulation of Reaction Coordinate J. American Institute of Physics. The definition and location of an intrinsic reaction coordinate path is of crucial importance in many areas of theor.
Differential equations used to define the path hitherto are complemented in this study with a variational principle of Fermat type, as Fukui [Int. Quantum Chem. This definition is more suitable for problems where initial and final points are given. The variational definition can naturally be recast into a Hamilton-Jacobi equation.
The character of the variational soln. The characterization of the local min. Such result leads to a numerical algorithm to find intrinsic reaction coordinate paths based on the successive minimizations of the Weierstrass E-function evaluated on a guess curve connecting the initial and final points of the desired path.
