Using IR Frequencies to Compare Bond Strengths via Harmonic Oscillator Model
Inorganic chemists often use IR spectroscopy to evaluate bond order of ligands, and as a means of determining the electronic properties of metal fragments.

This is a nanochemistry lab I developed for my Junior and Senior level Inorganic Chemistry course. I am NOT a nano/matertials person, but I know how important nanochemistry is and I wanted to make something where students could get an interesting introduction to the area. The first time I ran this lab was also the first time I made gold nanoparticles ever!
We do not have any surface/nano instrumentation here (AFM, SEM/TEM, DLS, etc... we can access them at other universities off-campus but that takes time and scheduling), so that was a key limitation in making this lab.
In honor of Professor Richard Andersen’s 75th birthday, a small group of IONiC leaders submitted a paper to a special issue of
For inorganic lab, I have my students write their lab reports in the style of the journal Inorganic Chemistry. The first week of lab, we spend time in small groups looking at several examples of recent articles from Inorganic Chemistry, focusing mainly on the experimental section and the abstract (as these are included in every lab report). We then come back together as a class to have a discussion of each of the sections in the articles. We discuss what was included in each section, what wasn’t included, and the style, tone, tense, and voice of each section.
Modern theories of atomic structure and chemical bonding and their applocations to molecular and metallic structures and coordination chemistry.
Introduction to classical and modern techniques for
synthesizing inorganic compounds of representative and transition
metal elements and the extensive use of IR, NMR, mass, and UV-visible
spectroscopies and other physical measurements to characterize
products. Syntheses and characterization of inorganic and organic
materials/polymers are included. Attendance at departmental seminars
required. Lecture, laboratory, oral presentations.
This course uses molecular orbital theory to explain the electronic structure and reactivity of inorganic complexes. Topics include symmetry and its applications to bonding and spectroscopy, electronic spectroscopy of transition-metal complexes, mechanisms of substitution and redox processes, organometallic and multinuclear NMR.
Additional notes
I do not require a formal text but George Stanley's organometallic chemistry 'book' on VIPEr is made available to students (the link is found below).
Introduces the theories of atomic structure and bonding in main-group and solid-state compounds. Common techniques for characterizing inorganic compounds such as NMR, IR, and mass spectrometry are discussed. Descriptive chemistry of main group elements is examined. Conductivity, magnetism, superconductivity, and an introduction to bioinorganic chemistry are additional topics in the course. In lieu of the laboratory, students have a project on a topic of their choice. Serves as an advanced chemistry elective for biochemistry majors.
