On the emission spectrum of molecular SbF
Journal of Physics B: Atomic and Molecular Physics, 1973The visible bands of SbF molecule have been photographed in a high frequency discharge at a dispersion of 7.5 AA/mm in the first order of a plane grating spectrograph. A new band system in the region lambda lambda 4730-5770 AA belonging to this molecule has been analysed and the vibrational constants are determined.

THE EMISSION SPECTRUM OF THE CCI RADICAL
Canadian Journal of Physics, 1961A rotational analysis of the 2780 Å emission band obtained in a microwave discharge through CCl4 vapor and photographed on a 20-ft grating spectrograph shows that a 2Δi(b) → 2Πr(a) transition of the CCl radical is responsible, not 2Σ → 2Π(a) as reported by previous workers.

Chemistry of Materials, 2019
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

Physical Review A, 1987
The two-photon emission spectrum of a strongly driven two-level atom is defined and calculated. Such a spectrum reveals details of non-Markovian dynamics which are not observable in the usual experiments. It is shown that a clear separation of Markovian and non-Markovian regimes is possible in the two-photon emission spectrum.

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.

The emission band spectrum of GaBr
Physica, 1974Abstract The emission band spectrum of gallium monobromide in the region λ3700–λ3400 A excited in a radio-frequency discharge is photographed in the first-order dispersion (1.25 A/mm) of a 21 ft concave grating spectrograph. The spectrograms taken under high resolution reveal the presence of about 100 new bands which are assigned to the two ...

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

On the spectrum of fluctuations in the field emission
Proceedings International University Conference 'Electronics and Radiophysics of Ultra-High Frequencies' (Cat. No.99EX356), 2003The influence of probabilistic assumptions that determine the statistical model of multistable fluctuations in the field emission on the theoretical noise spectrum shape is studied.

Spectrum of the Galactic Radio Emission
Nature, 1965A NEW series of observations of the galactic radio emission has been conducted at the frequencies of 20, 30 and 85 Mc/s. These low-resolution observations made with scaled aerials were intended to investigate the spectral index of the galactic radio emission in the frequency region 10–100 Mc/s.

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.
