The effect of organi c so 1 vents on tion absorption in air-hydrogen flames has been investigated. In present studies the effect of organic solvents found depended very much on the fuel/oxidant ratio of the flame. It has been found that solvents increased the tin absorption in fuel-lean flames while in fuel-rich flames they depress it. These studies sign~ficantly extend the present knowledge of behaviour of tin atoms in air-hydrogen flames. In this part of work the effect has been established by using various sovlents, flames and metals and by changing other parameters such as flame height etc.
