Identifying quintet states at room temperature via nutation experiments. a Nutation experiment for the high-field quintet and triplet transitions, with the pulse sequence shown in the inset. b Fourier Transform of data in a showing a ratio of 1.74 between the triplet and quintet nutation frequencies (16.85 and 29.3 MHz, respectively), in accord with the nominal value of √3 = 1.73
