Fluorescence and stimulated emission S1 → S0 spectra of acetylene: Regular and ergodic regions
TL;DR: In this paper, the S1→S0 transition of acetylene has been studied by spontaneous and stimulated emission and two new vibrational constants, y224 and y244, were determined.

The Ã-X̃ band system of acetylene: Analysis of long-wavelength bands, and vibration-rotation constants for the levels nν″4 (n = 0–4), nν′3 (n = 0–3), and ν′2 + nν′3 (n = 0–2)
TL;DR: In this paper, the rotational structures of the vibrational levels of the nonlinear A state were fitted with asymmetric top rotational constants A v, B v, C v and principal centrifugal constants D v J, D vJK, Dv K.

The electronic states of pyrrole studied by optical (VUV) absorption, near-threshold electron energy-loss (EEL) spectroscopy and ab initio multi-reference configuration interaction calculations
TL;DR: In this paper, a reinvestigation and extension of the observed VUV and EEL spectrum of pyrrole has been carried out, and the spectra assigned by means of high level multi-reference multi-root CI studies.
Journal ArticleDOI
Triplet electronic states of acetylene: cis and trans structures and energetics
TL;DR: In this article, the double zeta (DZ) and double Zeta plus polarization basis sets of Gaussian functions were used, in conjunction with self-consistent field (SCF) and large scale configuration interaction (CI) wavefunctions.
Journal ArticleDOI
Photochemistry of acetylene at 1849 Å
TL;DR: In this article, the photochemical process of acetylene at 1849 A may represent that of the Titan atmosphere in the Jovian and Titan atmospheres, and the amount of diacetylene produced was measured on the basis of absorption near 1650 A.

HIGH-RESOLUTION STUDY OF ELECTRON-IMPACT SPECTRA AT KINETIC ENERGIES BETWEEN 33 AND 100 eV AND SCATTERING ANGLES TO 16--.
TL;DR: An electrostatic lens system which compensates for chromatic aberration has been tested in an electron spectrometer and the results indicate that this lens is suitable for comparisons of peak intensities in electron impact spectra.

Analysis of the Near Ultraviolet Absorption Spectrum of Acetylene
TL;DR: In this paper, it has been shown that the upper electronic state is Au or possibly Ag and the effective moment of inertia Ia of the excited state is small, causing sub-band separations of 50 to 150 cm.

Absorption and Photoionization Coefficients of Acetylene, Propyne, and 1‐Butyne
Toshio Nakayama,Kiyoaki Watanabe +1 more
TL;DR: In this article, the authors measured the absorption coefficients of acetylene, propyne and 1-butyne using a photoelectric technique in the region 1050-2000 A. The photoionization curves and the Rydberg series yielded the same ionization potential: 11.41, 10.36, and 10.18 eV.
