Schlegel, H. B. (1990). "Geometric Phase in the Intrinsic Reaction Coordinate." Journal of Physical Chemistry*, 94(18), 6829-6835.

This citation has the wrong page numbers. If you go to the Physical Chemistry website you will see the volume and page numbers don’t come together that way in the 1990 publications.

Here’s a link to all the articles that H. B. Schlegel did publish in the Journal of Physical Chemistry.

It put your three articles into AI - Here's their response!

he articles and book titles you referenced seem to have incorrect titles or bibliographic details. I can guide you on how to search for them or related materials. Here are some suggestions:

1. Schlegel, H. B. (1990)

• The author H. Bernhard Schlegel is well-known for his work in computational chemistry, especially on intrinsic reaction coordinates (IRCs) and electronic structure methods. However, the specific article, "Geometric Phase in the Intrinsic Reaction Coordinate," does not seem to exist.
• You can find Schlegel's actual work on IRC and related topics in databases like:Google Scholar: Google Scholar Search American Chemical Society (ACS): ACS Publications Journal of Physical Chemistry A/B/C: His papers are often in these journals.

2. Gao, J., & Truhlar, D. G. (2002)

• The authors Jiali Gao and Donald G. Truhlar are prominent in theoretical chemistry. They have many well-known papers on IRC theory. However, the title "Theory and Applications of the Intrinsic Reaction Coordinate" doesn't match their known publications.
• You can explore their actual works on IRC and related theoretical chemistry topics in:Chemical Reviews: Look for their articles under ACS Chemical Reviews.

3. Frenking, G., & Froese Fischer, C. (2014)

• Gernot Frenking is a leading figure in theoretical chemistry, and Charlotte Froese Fischer is known for her work on atomic structure calculations.
• The book "Theoretical Methods in the Study of Organic Chemistry" doesn't match their actual titles. Frenking has contributed to theoretical chemistry literature, but this title might be inaccurate.
• Check out:Wiley Online Library: Wiley Publications Books by Frenking: "Theoretical Chemistry in Organic Chemistry" and other works may exist with slightly different names.

Additional Search Tips

• Google Scholar is a powerful resource for verifying authors and articles: Google Scholar
• CrossRef and Web of Science are useful for more detailed bibliographic searches if you're part of an institution.

Dear Fatemeh Razavi As indicated by Madelaine Lawrence the references are incorrect. Even stronger: I think the references are fake and non-existing. I suspect that they are AI generated. See for example https://teche.mq.edu.au/2023/02/why-does-chatgpt-generate-fake-references/

Best regards.

Yes, a fake citation. How or by whom it was generated is open to debate.
