Refractive Index Measurements on Fused LiNO 3 , RbNO 3 and CsNO 3 with a Modified Thermooptic Technique

A modified method for measuring absolute values of the refractive index and its temperature dependence is presented. A direct comparison is made between the refractive index of a liquid sample and ambient air. Values for LiNO 3 , RbNO 3 , and CsNO 3 within a temperature interval of about 80 K above...

Zusammenfassung:A modified method for measuring absolute values of the refractive index and its temperature dependence is presented. A direct comparison is made between the refractive index of a liquid sample and ambient air. Values for LiNO 3 , RbNO 3 , and CsNO 3 within a temperature interval of about 80 K above the melting point for several different wavelengths are presented as well as the calculated values of the molar refractivity and the absorption lines of the NO 3 - ion.
