Measurement of the physical properties of cyclohexane using a laser interferometric technique

A laser Mach-Zehnder interferometric modified technique providing the necessary high precision measurements of the physical properties of the most frequently used solvents for laser dyes is applied. This technique offers several advantages in the determination of the absolute Value of the refractive index of cyclohexane (C6H12) at 20 degrees C for a wavelength 632.8 nm and also its thermal coefficient. About fourteen various macroscopic and microscopic physical constants that can be derived from the refractive index are presented. In comparison with the other methods described in the literature, the accuracy and sensitivity of this technique are discussed.
