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.

Very cute toy
I THOUGHT IT WOUKD BE BIGGER. it's about the size of 24 oz water bottle. Kinda small in my opinion. The dogs loved it but I've had it a week and it's already torn apart....my dogs are only about 3 months old so not very strong yet, so I would say it's like mid quality. I'll probably just sew the seam back together and call it good tbh.

My yorkie destroyed
It says it’s very durable so that’s why I bought it although the body and ropes are good the ears on the horse came off in the first day with my small dog so be careful with the ears and other looser things on the animals. The rope untied many times as well not a big deal I just knotted it back but she still loves this toy so it’s okay I’m my book just watch for ripping of ears and other parts on the head of this toy

Head and body ripped after less than 5 min of tug
Color: Scrunch Bunch Bunny, Color: Scrunch Bunch Bunny
The seam beteeen the head and body failed after less than five minutes of supervised tug with a 35 pound dog. This is NOT a tough toy. No reinforced stitching.
Absolutely unsafe - a dog could easily rip open the neck and get at the squeakers, which are small enough to be swallowed and lodged in an intestine.

Good but not as tough as advertised
Color: Scrunch Bunch Duck
My dog absolutely loved this toy. He was obsessed immediately! It was his (and our) first crinkle toy. He loves the crinkle though it’s a bit distracting for me as it kind of sounds like he’s getting into something he shouldn’t. I love that there are two squeakers, one in the belly and one in one of the handles to squeak on during tug of war. Though he enjoys this toy, the head ripped off during a mild tug only about a few hrs after delivery. My dog is a medium sized 25 lb dog, he is not super strong or a super chewer by any means so I was surprised that it tore so easily. The fabric itself seems strong enough to withstand mild chewing but the seams aren’t as tough as they are advertised. If you don’t mind mending your dogs toys, it’s a very fun toy that’s easy to play with your dog as the handles work well for tug of war, just keep in mind that anything over a small sized dog will probably tear this toy apart during a play session.
