This video talks you through the reaction mechanism of the Beckmann rearrangement. The video shows both the curly arrows and how the curly arrows relate to the molecular orbitals that play a role in the rearrangement reaction. The video is part of a series of videos to help you understand more organic chemistry so that you have to learn less organic chemistry.

In this video, I show how you can use CAS numbers to find articles about specific chemical compounds in the Scopus database. This is particularly useful when writing a literature review, introduction, essay, etc. in chemistry or a related discipline.

In this video, I show how you can use a key paper on a topic of interest (such as molecular machines as illustrated by Ben Feringa's nanocar) to find recent papers on the same topic using scopus. This trick is useful when writing a literature review or an essay on a topic in chemistry.

This video shows how to use excel to calculate total concentrations of compounds at every point of a UV-visible titration. The example involves titrations of small molecules with DNA, but the principles apply to other titrations as well. If you would like a copy of the spreadsheet I use in the video, just send me an email.

This video shows how you create a contour plot in Origin using regular x,y,z data from an excel spreadsheet.

This video shows how a non-linear from of the integrated rate law for first order kinetics can be fitted to experimental data. The video shows a global fit where multiple datasets are analysed simultaneously (global fit) to give a single first-order rate constant.

This video shows how you can add a function definition file, containing an equation describing the first-order rate law, to the Origin data analysis software.

This video demonstrates how to extract the most relevant kinetic traces (allowing data analysis in terms of kinetic rate laws) from a series of spectra recorded over time for a chemical reaction.

This video shows how to generate overlay spectra and difference spectra from combined spectra in an excel file.

This video shows how you can manually combine data stored in txt files (for example data exported from a UV-visible instrument) into a single excel file for data analysis and data plotting using a slightly quicker method than the method shown in from spectra to kinetics 01.

This video shows how you can manually combine data stored in txt files (for example data exported from a UV-visible instrument) into a single excel file for data analysis and data plotting.

This video shows an easy way of creating pictures of nucleic acid structures with and without binders using UCSF Chimera using PDB files available from the nucleic acids database. The resulting pictures of different DNA structures are great for for reports, theses, powerpoint presentations and posters.
