We measured Raman spectra of N2fluids obtained at 0.1–25 MPa at room temperature. The14N15N peak in the Raman spectrum of a low‐pressure N2fluid is difficult to detect because of the prevalence of a group of peaks attributed to rotational vibration of14N2. The Raman peaks of14N15N and14N2of N2fluid at 25 MPa were acquired at various exposure times. The mean values and standard deviations of the peak height ratios and peak area ones of14N15N and14N2were examined for each time. The standard deviations of the peak height ratios and peak area ones were 2.2% and 1.9%, respectively, for 20 spectra acquired with peak height of 1 million counts of14N2. The uncertainties are about two times higher than those predicted from the noise of a CCD. Improvement of the pixel resolution can enhance the precision of the nitrogen isotope ratios by Raman spectroscopy.
