Introduction to Pulsed Gradient Spin Echo DOSY

Submitted by Jacob Lutter / University of Southern Indiana on Thu, 02/08/2018 - 14:35
Description

Pulsed Gradient Spin Echo (PGSE) DOSY is a NMR technique used for determining the hydrodynamic radius of a molecule in solution by measuring the rate of diffusion. This technique requires a standard, usually tetrakis(trimethylsilyl)silane (TMSS). This activity will cover the basics of how PGSE works and includes built in animations to demonstrate how the nuclear magnetization is affected. Each slide has comments explaining the content for the user's convenience.

Foundations of Inorganic Chemistry

Submitted by Sabrina Sobel / Hofstra University on Mon, 01/22/2018 - 14:58
Description

Fundamental principles of inorganic chemistry, including: states of matter; modern atomic and bonding theory; mass and energy relationships in chemical reactions; equilibria; acids and bases; descriptive inorganic chemistry; solid state structure; and electrochemistry. Periodic properties of the elements and their compounds are discussed (3 hours lecture, 1 hour recitation).

Description

Modern theories of atomic structure and chemical bonding and their applocations to molecular and metallic structures and coordination chemistry.

Isomerism in Coordination Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/18/2018 - 12:07
Description

Students are confronted with a number of new types of isomerism as they move from organic chemistry into inorganic chemistry. This can be confusing and students often have trouble visualizing structures and differentiating between isomers. In this exercise, students are asked to examine a number of different crystal structures from the Teaching Subset (distributed with Mercury version 3.10, early 2018) of the Cambridge Structural Database.

Metal Tropocoronand Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 01/17/2018 - 13:36
Description

This exercise looks at the metal complexes of tropocoronand ligands, which were first studied by Nakanishi, Lippard, and coworkers in the 1980s. The size of the metal binding cavity in these macrocyclic ligands can be varied by changing the number of atoms in the linker chains between the aminotroponeimine rings, similar to crown ethers. These tetradentate ligands bind a number of +2 metal centers (Cd, Co, Cu, Ni, and Zn) and the geometry of the donor atoms around the metal center changes with the number of atoms in the linker chains.

Inorganic Chemistry II

Submitted by Chip Nataro / Lafayette College on Mon, 01/15/2018 - 14:03
Description

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).

Inorganic Chemistry I with Laboratory

Submitted by Chip Nataro / Lafayette College on Mon, 01/15/2018 - 12:17
Description

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.

Geometry Indices

Submitted by Anthony L. Fernandez / Merrimack College on Fri, 01/12/2018 - 23:20
Description

In the primary literature, goemetry indices are being used quite often to describe four- and five-coordinate structures adopted by transition metal complexes. This slide deck, which is longer than the intended 5 slides, describes the three common geometry indices (tau4, tau4', and tau5) and provides example calculations for structures that are freely available in the Teaching Subset of the Cambridge Structural Database. (Students can access these structures in Mercury, which is freely available from the CCDC, or via a web request form for which the link is provided below.)
