Abstract
The Raman spectrum of hexadecane (n‐C16) has been analyzed in the high frequency C–H stretching region (2800–3100 cm−1). The intensity of the bands was studied as a function of the concentration of n‐C16 when it was diluted in the low molecular weight, quasispherical solvent CDCl3. This solvent does not exhibit any Raman active bands in the region of interest. In order to characterize the influence of the concentration on the local order, parallel studies were conducted on both neat n‐C16 and a very dilute solution of n‐C16 in CDCl3 as functions of temperature. A comparison of these three series of spectra suggests that the neat liquid exhibits about 5% higher t r a n s bond content than does the dilute solution.
