A molecular spectroscopic method has been developed to estimate the10B concentration in BF3. This method makes use of the isotopic displacements in the R1 heads of the BO2 band at 5457Å. The emission spectrum of the BO2 radical was obtained in a microwave oscillator discharge through BF3 and an excess of argon, having oxygen as trace impurity. The intensities of the R1 heads were measured for different standards containing 20 to 90 per cent. of 10B in BF3. The standard deviation varies from 1.7 to 2.7 in the above concentration range.
