Preface
These are our own solutions to the problems in Introduction to Quantum Mechanics, 3rd ed. We have
made every effort to insure that they are clear and correct, but errors are bound to occur, and for this
we apologize in advance. We would like to thank the many people who pointed out mistakes in the solu-
tion manual for the second edition, and encourage anyone who finds defects in this one to alert us (grif-
fith@reed.edu or schroetd@reed.edu). We especially thank Kenny Scott, Alain Thys, and Sergei Walter,
who found many errors in the 2nd edition solution manual. We maintain a list of errata on the web page
(http://academic.reed.edu/physics/faculty/griffiths.html), and incorporate corrections in the manual itself from
time to time. We also thank our students for many useful suggestions, and Neelaksh Sadhoo, who did much of
the typesetting for the second edition.
