Elementary Quantum Chemistry, Second EditionAs the author notes in the Preface to this valuable text, experimental chemists have moved past studying the average behavior of atoms or molecules "to probe the step by step behavior of individual atoms and molecules as they collide, form 'transition states, ' and ultimately form products."

As the author notes in the Preface to this valuable text, experimental chemists have moved past studying the average behavior of atoms or molecules "to probe the step-by-step behavior of individual atoms and molecules as they collide, form 'transition states, ' and ultimately form products." In such experiments, quantum mechanical computations do two useful tasks: They fill in the observational gaps and help to interpret what has been observed.This introductory course -- developed by the former chairman of the chemistry department at the University of New Hampshire -- covers, among other topics, the origins of the quantum theory, the Schr dinger wave equation, the quantum mechanics of simple systems, the rigid rotator, the hydrogen atom, electron spin and many-electron systems, the quantum states of atoms, the Hartree-Fock self-consistent field method, the electronic structure of molecules, and semi-empirical molecular orbital methods. One of the great values of the course is its calculations and diagrams, which were created specifically for this text and which students will be able to replicate on their home computers.
The text will be most useful for advanced undergraduate or beginning graduate students who have had calculus and at least a year of undergraduate physics. A knowledge of differential equations, linear algebra, and atomic physics is helpful but not essential. Seven appendices give a concise exposition of mathematical and physical material that may not be part of the students' background.

Nice and sturdy.
Color: Black*2Pack
This system worked for what I needed. The metal wire trays are well-made and big enough to handle larger power strips. I was concerned when ordering it, as I have had to return several in the past, from other companies that were just too small. These, along with the wire holders, made channeling the wires behind my desk rather easy.

These worked out well
Color: Black*2Pack
These worked out well. One of the two baskets was bent a little so I had to adjust to make them match. The baskets are strong and they are holding multiple power supplies without issues. I don't prefer self tapping screws but I pre-drilled small pilot holes and they worked fine.

Racking Solution for Networking Devices
Color: White*2Pack, Color: White*2Pack
Guess I need to clean that wall...
It's not noticeable in person but really came out in these pics lol
THE REVIEW
I bought these because I wanted to clean up and my networking setup.
I refuse to get an all-in-one device from my cable provider, opting instead to purchase my own modem, router (Netgate), switch, and access point (Unifi Cube).
This ends as spaghetti and meatballs setup of cables and devices. Nothing beats a racking system for isolating components, protecting them, airflow for cooling, etc.
I've attached a couple of pics of the setup. From ground up, you go through modem, router, 10-port managed switch, and out to wifi access point and secondary 5-port switch that are in other rooms.
I wanted something that would:
- Get these off of the desk level in case of another coffee spill ;-)
- Separate them enough to where they can breath without sucking up heat from one another
- Keep cables neat/organized
This turned out to be a very inexpensive and perfect solution.

Highly recommended
Color: White*2Pack
Keep my cables very organized. The size is perfect to fit the battery of my stand table and cables. Very easy to install. Great product for the money you pay.
