-Four transitions with //J// = 19 − 18 or 18 − 17 and //v// = 0 or 1 were observed with ALMA toward the G351.77-mm1 protostellar disk. Three lines are blended, but the one with //J// = 19 − 18 and //v// = 0 at 200.714 GHz is partially clear and the //J// = 18 − 17 and //v// = 1 at 189.261 GHz apparently helps to constrain //T//<sub>rot</sub> and the column density. //J// = 22 − 21, //v// = 0, at 232.372 GHz was covered by archival ALMA data, and the high-resolution recording suggests this line dominates at least part of the emission feature. The same extent as NaCl and the value of //T//<sub>rot</sub> can be viewed in support of the assignment. Slight caution may be advised nevertheless until further lines will have been detected.+Four transitions with //J// = 19 − 18 or 18 − 17 and //v// = 0 or 1 were observed with ALMA toward the G351.77-mm1 protostellar disk.
