Dear Professor Sheline:
I am pleased to have your letter and I look forward to receiving the sample of 5 grams of dicobalt octacarbonyl, prepared by Dr. Sternberg of the U.S. Bureau of Mines. We shall plan to purify the material as recommended in your letter.
I thank you for the copy of your paper on the infrared studies of dicobalt octacarbonyl. I read the manuscript yesterday, and in the course of reading it I thought of another structure, which you have not considered. I have not yet carefully checked the infrared spectrum predicted for this structure, but I shall let you know as soon as this is done.
Sincerely yours,
Linus Pauling:W
