SERMACS 2025 call for Papers

Submitted by Carl Ohrenberg / University of North Georgia on Wed, 07/23/2025 - 12:10

My colleague and I at the University of North Georgia have organized a symposium on Effective ways to Teach Inorganic Chemistry at the Southeast Regional ACS meeting in Orlando in October.  We need presenters and abstracts are due next Monday (7/28).  Those of you in the southeast region with new approaches to teaching please consider submitting an abstract.

Is 3d or 4s lower-energy in Sc and Ti? Do Sc+ and Ti+ have any 4s electrons?

Submitted by Joseph Keane / Muhlenberg College on Tue, 08/13/2024 - 19:28

Folks,

Unless I am mistaken, there are gross disagreements between Miessler & Tarr (5th ed) and the analyses by W. H. Eugen Schwarz (J. Chem. Ed. 2000, 435-443 and 444-448) about the energy levels of the valence orbitals in early transition metals and, subsequently, whether there are any electrons in 4s for the M+ ions.

A popular diagram (Figure 2.12) on p. 35 of M&T shows 4s below 3d up through vanadium and 1 electron in the 4s orbitals for each of Sc+, Ti+, Mn+, and Fe+.

Web based NMR processing

Submitted by Martin Chin / University of Northern Iowa on Tue, 09/27/2022 - 13:50

I have started using this for our students to process and analyze their NMR spectral data. I love that it is web based, so the students can use it anywhere and are not restricted to the computer lab or have to download software. I think they have worked out (or are working out) the kinks for handling JEOL data. I am not sure how it does with Bruker data. I assume it works fine for Bruker data.

New edition of my textbook Principles of Inorganic Chemistry

Submitted by Brian Pfennig / Ursinus College on Fri, 01/21/2022 - 13:37

A new edition of my textbook Principles of Inorganic Chemistry (2e) is now available on the Wiley website. You are welcome to request a digital examination copy at this site. For instructors who adopt the textbook, you can also download a Solutions Guide to the end of chapter problems. The second edition is more suitable for use at the undergraduate level than was the first and has been rewritten to have a more engaging and conversive style. The structure of the chapters has also changed. Please check it out.

ambidentate ligands - kinetics versus thermodynamics

Submitted by Joshua Telser / Roosevelt University on Fri, 04/23/2021 - 12:37

I scanned through the forums that came up with "kinetics" and could not find what I am looking for, but I know VIPEr people know the answer to this question: I am looking for an example of kinetics versus thermodynamics control of an ambidentate ligand, i.e., M + XY ---> M-XY initially (kinetics control) ---> M-YX (eventually, thermodynamic product). Any examples of M and XY (obviously "XY" is generic, could be SCN-, et al.)?

Help Getting teaching 2nd Semester Advananced Inorganic

Submitted by Lary / Wright State University on Fri, 01/15/2021 - 12:44

I am just starting teaching our 2nd semester Advanced Inorganic chemistry Course.  Essentially, the only information I received from my predecessor is that we use Miessler and teach chapters 10,11, 12,13, and 14.  I have the slides from the publisher.  Students have all had P.Chem. and the first semester Chapters 1-9 and are mostly seniors.
