چکیده

The lifetime of the b Pu(v51) state in N2 has been determined experimentally using a laser-based pump–probe scheme and an exceptionally long lifetime of 2.61 ns was found. Semiempirical close-coupling calculations of the radiative lifetime, which include Rydberg–valence interactions in the singlet manifold, are consistent with this large value, giving a value of 3.61 ns and suggesting a predissociation yield of ;28% for this level of the b state. © 2004 American Institute of Physics. @DOI: 10.1063/1.1704640#

Structure and predissociation of the 3psigma(u)D (3)Sigma(u) (+) Rydberg state of N(2): first extreme-ultraviolet and new near-infrared observations, with coupled-channels analysis.

The 3psigma(u)D (3)Sigma(u) (+) Rydberg state of N(2) is studied experimentally using two high-resolution spectroscopic techniques. First, the forbidden D (3)Sigma(u) (+)-X (1)Sigma(g) (+) transition is observed for the first time via the (0,0) band of (14)N(2) and the (1,0) band of (15)N(2), using 1 extreme-ultraviolet +1 ultraviolet two-photon-ionization laser spectroscopy. Second, the Rydber...

Isotope dependent predissociation in the C 1 Σ + , v = 0 and v = 1 states of CO

Rotationally resolved spectral lines in the C−X(1, 0) band of carbon monoxide are investigated under high resolution using a coherent vacuum ultraviolet laser source, continuously tunable near 107 nm. Transition frequencies are determined by calibrating against a reference standard of iodine lines, recorded with saturation spectroscopy in the visible range, yielding an absolute accuracy of 0.00...

Oscillator strengths and line widths of dipole-allowed transitions in (14)N2 between 86.0 and 89.7 nm.

Oscillator strengths of 23 electric-dipole-allowed bands of (14)N(2) in the 86.0-89.7 nm (111,480-116,280 cm(-1)) region are reported from synchrotron-based photoabsorption measurements at an instrumental resolution of 6.5x10(-4) nm (0.7 cm(-1)) full width at half maximum. The absorption spectrum comprises transitions to vibrational levels of the c(n) (1)Pi(u) (n=3,4), o(3) (1)Pi(u), and c(n+1)...
