Abstract Cyanogen absorption, excitation and dispersed fluorescence spectra have been measured in the 220 nm region. The radiative lifetime is 1.34 μs under collisionless conditions. The fluorescence spectrum following excitation of the 4 0 1 band consists of four simple progressions.

Nature, 1958
IN the course of a study of the luminescence of gases irradiated by X-rays (to be published), some unknown bands were observed from nitrous oxide. All the other gases studied emit well-known band systems, usually of the parent gas or its ion. Gases at pressures between 1 and 700 mm. were irradiated with soft X-rays (45 kV. peak) from a beryllium-window

A ground-based near-infrared emission spectrum of the exoplanet HD 189733b
Nature, 2010Detection of molecules using infrared spectroscopy probes the conditions and compositions of exoplanet atmospheres. Water (H2O), methane (CH4), carbon dioxide (CO2), and carbon monoxide (CO) have been detected in two hot Jupiters.

Abstract The radiation emitted from hot plasmas is, perhaps, the most important diagnostics tool for these plasmas. Recently, more effort is being invested into the investigation of this radiation, mainly in the UV and x-ray regions, because some industrial applications have emerged that may use such high intensity, localized short ...

Spectrum in Atomic Emission Spectroscopy
2021An atomic emission spectrum of aluminum is discussed as a typical instance. The spectral lines are assigned to electronic transitions between the energy levels of the aluminum atom, based on the Russell-Saunders coupling (LS-coupling) and the selection rule described in Chap. 12.

Infrared Emission Spectrum of KF
Journal of Molecular Spectroscopy, 1996Abstract The high-resolution infrared emission spectrum of potassium monofluoride has been recorded with a Fourier transform spectrometer. Over 900 vibration–rotation transitions, from the v = 1 → 0 to the v = 8 → 7 vibrational bands, have been assigned.

Infrared emission spectrum of calcite
Physica, 1956Abstract The polarized infrared emission and reflection spectra of calcite were measured at 300°C; the results are in quantitative agreement with Kirchhoff's law.

Finding new low-dimensional metal halides with broad-band emission is attracting interest in single-component phosphor for white light-emitting diodes (WLEDs). The full-spectrum white light still remains a challenge as found in the two-dimensional hybrid

Ultraviolet emission spectrum of ZnO
Solid State Communications, 1968Abstract The u.v. luminescence of ZnO has been measured in the temperature range 4.2°–77°K. Several new lines and bands have been observed. Two lines A L and A M (Thomas notation) have been reported in emission for the first time and some properties of these lines have been measured.
