The N = 0→ 1 and N = 1 → 2 transitions of 13C14N have been observed in a rf glow discharge in a CO + N2 + He mixture cooled at liquid nitrogen temperature. The 41 measured frequencies have been used to determine the rotational and fine structure constants as well as the hyperfine structure due to the 13C and 14N nuclei. Relative line intensities have also been calculated with a view to interstellar detection.

Abstract We report the results of optical emission spectroscopy measurements of rotational Trot and translational (gas) temperature of deuterium molecules. The light source was a low-voltage high-pressure hollow cathode (HC) glow discharge with titanium cathode operated in deuterium. The rotational temperature of excited electronic states of D2 was determined from the intensity distribution in the rotational structure of Q-branches of the two Fulcher-α diagonal bands: [ν′ = ν″ = 2] and [ν′ =ν″ = 3]. The population of the excited energy levels, determined from relative line intensities, was used to derive the radial distributions of the temperature of the excited and the ground state of the deuterium molecule.

A procedure is described to conduct qualitative analysis in inductively coupled plasma atomic emission spectrometry even in the presence of spectral interferences. This procedure is based on the use of both line correlation and normalized relative line intensities of given elements. When spectral interferences due to a major element are observed for an analyte, use of multiple linear regression of the normalized relative line intensities of both the analyte and the major element provides information about the certainty of the presence of the analyte and the relative concentration between the major element and the analyte. Direct peaking and automatic background correction are required for this procedure. In this instance, no information is necessary about the shape of the line profile. This procedure has been tested with an echelle grating-based dispersive system equipped with a custom segmented-array charge-coupled device detector.
