 **Note:** Questionable or rebuted detections have been omitted from the table. Some noteworthy cases are given below the table. Tentative detections, which have a reasonable chance to be correct, are indicated by "?". Usually the number of observed transitions that are, at least, fairly free of overlap is small. Some detections that have been reported as secure ones are indicated by "(?)" because (partial) overlap of lines cannot be ruled at the moment or because the line list is somewhat small; obviously, there may be cases on the edge. **Note:** Questionable or rebuted detections have been omitted from the table.

-As the decision whether a molecule can be considered as detected frequently is a controversial one we refrain from stating an exact number of molecules as detected. As of **November 2018**, 209 molecules have been detected in the interstellar medium or circumstellar shells; at least five of these are tentative detections, and for about five others, the situation is uncertain or a secure detection was called into questionIncluding some molecules missing (mainly metal compounds outside stellar atmospheres) in the table, the number of molecules detected in the ISM or in CSEs at least 199. Thus, we recommend phrases such as "**around 200 molecules** have been detected in the **interstellar medium or circumstellar shells**". Two reported detections have been questioned seriously. Therefore, these are viewed currently as "probably not yet detected" – see below. They do not show up in the table anymore.+As the decision whether a molecule can be considered as detected frequently is a controversial one we refrain from stating an exact number of molecules as detected. As of **Feb. 2024**, 307 molecules are listed in the section of interstellar or circumstellar molecules. Only few these are tentative or somewhat uncertain. On the other hand some molecules are still missing (mainly metal compounds outside stellar atmospheres) in the table. Thus, we recommend phrases such as "**more than 300 molecules** have been detected in the **interstellar medium or circumstellar shells**". Two reported detections have been questioned seriously. Therefore, these are viewed currently as "probably not yet detected" – see below. They do not show up in the table anymore.
  
-The number of molecules detected in extragalactic sources is 62 including one tentative detection. More may have to be added.+The number of molecules detected in extragalactic sources is **74** including three tentative detections. More may have to be added. The list includes protonated acetylene, C<sub>2</sub>H<sub>3</sub><sup>+</sup>, the first molecule detected in an extragalactic source, but not in a galactic source. The first species detected in an extragalactic but not galactic source is <sup>34</sup>SH<sup>+</sup> also in this peculiar foreground galaxy.

 The detection of SH by rovibrational spectroscopy of the S-type star R Andromedae has been omitted from this table as the molecule is present in the stellar atmosphere. It is hoped that a table of molecules in stellar atmospheres will be available in the not too distant future. Note, however, that the SH radical has recently been detected unambiguously in the ISM. The detection of SH by rovibrational spectroscopy of the S-type star R Andromedae has been omitted from this table as the molecule is present in the stellar atmosphere.
