'Twas the night before Christmas, when all through the house Not a creature was stirring, not even a mouse . . . It's Christmas Eve and the whole house is sleeping - all except one little boy, woken up by the jingle of bells and the clatter of reindeer hooves on the roof. As he tiptoes downstairs, who will he find? Mark Marshall's captivating illustrations places a little boy at the heart of Clement C Moore's classic Christmas poem. This bright and bold picture book is a perfect Christmas gift for young children - and a great way to introduce a new generation to this iconic poem. With a magical, glittery cover!

This Solutions Manual accompanies the second edition of Donald McQuarrie's Quantum Chemistry. It contains each of the more than 700 problems in the text, followed by a detailed solution. Written by chemistry faculty members Helen O. Leung and Mark D. Marshall, both of Amherst College, in conjunction with Prof. McQuarrie, each solution combines the clarity the authors use in teaching the same material in their own classrooms with the rigor appropriate to learning and appreciating an introduction to quantum chemistry. Both Helen Leung and Mark Marshall are recipients of the Henry Dreyfus Teacher-Scholar Award. They bring to the manual the insight gained from years of using quantum mechanics as spectroscopists with active research programs along with strong, effective pedagogy.
