抄録

Molecular absorption and emission spectra of calcium chloride and nitrate solution in air-acetylene flame were measured in the wavelength range from 200 to 650 nm. Absorption and emission spectra of CaO were measured in the wavelength range from 310 to 400 nm. Spectra of CaOH were measured in the wavelength range from 540 to 568 and from 614 to 640 nm. Especially, the spectrum of CaOH at 554 nm was absorbed strongly. The absorption spectrum of CaCl was obtained clearly in argon-hydrogen cool flame in the wavelength range from 200 to 280 nm. Then, the absorption of Ca atomic line and CaCl, CaO and CaOH molecular bands were measured as a function of hydrogen flow rate. The ratio of absorption of CaO and CaCl molecules compared with atomic Ca was greater in hydrogen lean flame. In hydrogen rich flame, the ratio of absorption of these molecules was decreased.
