A simple method for its determination from 13-C NMR line intensities has also been proposed.
2.
The analysis of line intensity ratios is an important tool to obtain information about laboratory and space plasmas.
3.
CO line intensities are calibrated using the room-temperature chopper-wheel method and the two-layer atmosphere model of Kutner ( 1978 ).
4.
By stepping the detectors along the angle, and leaving it in position for a known time, the number of counts at each angular position gives the line intensity.
5.
At the CO signal frequency the atmospheric opacity is appreciable, mostly due to molecular oxygen and water vapor, and corrections to the observed line intensities for signal attenuation must be applied.
6.
Since the measurement of an absolute intensity in an experiment can be challenging, the ratio of different spectral line intensities can be used to achieve information about the plasma, as well.
7.
For homonuclear diatomics, nuclear spin statistical weights lead to alternating line intensities between even-J ^ { \ prime \ prime } and odd-J ^ { \ prime \ prime } levels.
8.
The spectra of centrosymmetric molecules exhibit alternating line intensities due to quantum state symmetry effects, since rotation of the molecule by 180?about a 2-fold rotation axis is equivalent to exchanging identical nuclei.
9.
There are two types of fire intensity : reaction intensity, which is determined by the amount of heat released by the fire per unit of area burned and fire line intensity, which is determined by the length of the flames at the edge of the fire and height of scorch marks on affected trees.
10.
In the oft-encountered case of " I " = 1 / 2 nuclei ( e . g ., 1 H, 19 F, 31 P ), the line intensities produced by a population of radicals, each possessing " M " equivalent nuclei, will follow Pascal's triangle.
