(n.) An instrument for measuring the direct heating power of the sun's rays.
(n.) An instrument for measuring the actinic effect of rays of light.
Example Sentences:
(1) The quantum yield of the primary photoprocess in light-adapted bacteriorhodopsin (phi 1) was determined at room temperature with low-intensity 530 nm neodymium laser excitation, with bovine rhodopsin as a relative actinometer.
(2) The irradiation dose was determined by a modified potassium ferrioxalate actinometer according to Calvert and Pitts.
(3) The radiation in the visible and ultraviolet regions from submerged, transient electrical arcs was measured with a K(3)Fe(C(2)O(4))(3) chemical actinometer and was compared to the bactericidal effect obtained with the same electrical arrangements.
Actinometry
Definition:
(n.) The measurement of the force of solar radiation.
(n.) The measurement of the chemical or actinic energy of light.
Example Sentences:
(1) We have proceeded to the verification of their output with a spectrophotometer calibrated by actinometry and we have calculated their relative erythemal efficacy according to the Parrish's action spectrum for human erythema.
(2) The nature of the primary photochemical events in rhodopsin and isorhodopsin is studied by using low temperature actinometry, low temperature absorption spectroscopy, and intermediate neglect of differential overlap including partial single and double configuration interaction (INDO-PSDCI) molecular orbital theory.
(3) A fully corrected chemiluminescence monitoring spectrometer was calibrated for spectral sensitivity using the chemiluminescence of the bis-(pentachlorophenyl) oxalate system as a liquid light source, the total photon output of which had previously been determined by chemical actinometry.
(4) Therefore, it is considered feasible to simulate the photo-stability of KBT-3022 in aqueous solutions containing acetonitrile by exposure to all other light sources including diffuse daylight, if the cumulative number of photons of the light can be determined by actinometry.
(5) Actinometry of devices for ultraviolet irradiation of blood for the first time.
