| **Background:** Popular solid-state Nuclear Magnetic Resonance (NMR) techniques measure inter-atomic distances by observing the rate of transfer of magnetization between two spins by a spin diffusion mechanism. Plots of normalized magnetization... |
| The following demonstration shows the use of Discrete Variable Representation to estimate the eigenstates of a quartic potential. This demonstration is inspired by a homework problem in MIT Chemistry's graduate first-semester quantum mechanics... |
| I have written a function that can implement the Matrix Numerov method in a similar manner to [Pillai, et al at UW-Madison][1], except that this script can quickly be generalized to other potential functions and run in two lines of code. I have... |
| How do I generalize this function so it can take any matrix and, for each row, take the ratio of each element to the n'th element of that row? Mapping works if I want to use the default position I set, but not if I want to specify a position. ... |
| The medicinal value of drugs is optimized via Quantitative Structure-Activity Relationships, or QSAR. QSAR seeks to explain the variation in the biological activity of related molecules via variations in their structure and physicochemical... |
