Unblended and optically thin transitions of CH₃OD detected in V883 Ori. The observed spectra are plotted as gray histograms in the order of increasing frequency. The best LTE fit by fixing T_ex = 120 K is shown in red line and the overall fitting, i.e., by including the contribution from all other molecular species detected in V883 Ori in J.-H. Jeong et al. (2025), is in purple line. The quantum numbers and value of E_u of each transitions are listed on the upper part of each panel.
