Fluorescence is generally measured at a 90° angle from the excitation source to minimize collection of scattered light from the excitation source, often such a rotation is provided by a Pellin–Broca prism on a turntable which will also separate the light into its spectrum for closer analysis.
Excitation of string vibration is generally provided by a bow consisting of a flat ribbon of parallel horse hairs stretched between the ends of a stick, which may be made of wood or synthetic material such as fiberglass or carbon-fiber composite.
In astronomy, collisional excitation gives rise to spectral lines in the spectra of astronomical objects such as planetary nebulae and H II regions.
U.S. patent 3,941,136: "Method for artificially inducing urination, defecation, or sexual excitation".
The resulting influx of Ca2+ ions lead to the initiation of excitation-contraction coupling and thus contraction of the myocyte.
The method is spectrometric (fluorescent emission at 436-475 nm (max 455 nm) with excitation at 330-390nm (max. 340 nm)).
The dual effect of seletracetam is an overall decrease in the amount of action potential due to binding at N-type channels, which prevents over-excitation of the neuron, as well as a decrease in neurotransmitter release as a product of cellular excitation due to the interaction of the drug with SV2A, which reduces the spread of excitation to nearby cells.
Gamma and theta oscillations, released during exploratory activities, create modulated rhythms that transform into prolonged excitation, and furthermore into memories or improper potentiation.
1941 - Andrew McKellar uses the excitation of CN doublet lines to measure that the "effective temperature of space" is about 2.3 K
In 2008, a team at GANIL, France, published results indicating that nuclei of unbiquadium had been produced at very high excitation energy, which underwent fission with measurable lifetimes.
