 The authors report a tentative detection of torsionally excited CH<sub>3</sub><sup>18</sup>OH in the ReExploring Molecular Complexity with ALMA survey at 3 mm besides several a clear identification of this isotopolog in its ground torsional state.\\ The authors report a tentative detection of torsionally excited CH<sub>3</sub><sup>18</sup>OH in the ReExploring Molecular Complexity with ALMA survey at 3 mm besides several a clear identification of this isotopolog in its ground torsional state.\\

 +More than 70 transitions were detected with EXES on board of SOFIA toward the massive protostar NGC 7538 IRS 1. Most of the transitions belong to the torsional overtone 2//v//<sub>12</sub>, some also to the torsional fundamental //v//<sub>12</sub>. The derived rotational temperature as well as the column density agree with submillimeter observations.\\
