- Other information
 | This image is in the public domain in the United States because it was first published outside the United States prior to January 1, 1929. Other jurisdictions have other rules. Also note that this image may not be in the public domain in the 9th Circuit if it was first published on or after July 1, 1909 in noncompliance with US formalities, unless the author is known to have died in 1953 or earlier (more than 70 years ago) or the work was created in 1903 or earlier (more than 120 years ago.)[1] |  |
| This file will not be in the public domain in both its home country and the United States until January 1, 2028 and should not be transferred to Wikimedia Commons until that date, as Commons requires that images be free in the source country and in the United States. |
 | The uploader or another editor requests that a local copy of this file be kept. This image or media file may be available on the Wikimedia Commons as File:Stark model of triatomic hydrogen.png, where categories and captions may be viewed. While the license of this file may be compliant with the Wikimedia Commons, an editor has requested that the local copy be kept too. This file does not meet CSD F8 and should not be tagged as a Commons duplicate. If you desire to nominate it for deletion, notify the tagging editor. |  |
I am unsure that this would be public domain in original country Germany, as Stark died in 1957.
