    7 April 1955

    Professor Fred Allen

    Purdue University

    Lafayette, Indiana

    Dear Fred:

    I am pleased to have received your letter today. I shall hasten to answer it, because Ava Helen and I are leaving on Sunday, on a week's trip east. Perhaps I shall see you in June anyway - I am looking forward to being there at the dedication of your new building.

    We had a fine time on the trip around the world. I got back to find the galley proofs waiting for me, and now I shall have page proofs to read while we are back east. Also, Ava Helen will have to make out the index.

    I am pleased at the prospect of your being here next year, for part of the year.

    Sincerely yours,

    Linus Pauling :W

  • Letter from LP to Dr. Gladys A. Anslow, Physics Dept., Smith College RE: Thanks Anslow for her invitation to visit Smith College laboratories.

  • Letter from LP to Per Hallvard Nilsen, Chemical Engineer, Chemical Products Division, Sarpsborg, Norway, RE: Does not agree with Nilsen's values for the resonance energies of aldol and DHD. Believes there is no reason for them to have resonance energies at all. Nilsen's reaction A might indeed be more exothermic than it is as calculated from bond energies, since the hydroxyl group and the aldehydic oxygen atom would be expected to form a hydrogen bond. Agrees that the bond energies predict the reaction B should be endothermic. Bonds energies for double bonds are not very reliable, but LP is still surprised that Nilsen found such a great discrepancy. [Letter from Nilsen to LP March 30, 1955] [Filed under LP Correspondence: (N: Correspondence), #287.22]
  • Letter from LP to Professor E.W. Pfeiffer, RE: Thanks Pfeiffer for the clipping that he sent. LP was also disturbed by the David Lawrence article and by an article about radioactivity that was published in U.S. News and World Report. Believes that either the writers or the publishers of that work were attempting to mislead the public. Encloses a copy of the release that he prepared for some television showings and a reprint of Professor Sturtevant's recent article.

Beckel, Physics Dept., Georgetown University, RE: Responds to request for advice on the importance of performing vibrational analyses of several potential curves for the ground state of the hydrogen molecule. A student named Bruchner is performing a similar study on the nitrogen molecule. Results have not been very encouraging so far, and do not indicate the rapid convergence of vibrational levels that LP had expected. LP does not think that the hydrogen molecule would be a good one to investigate because the normal state of the hydrogen atom is essentially the valence state of the atom in the molecule.

  • Letter from Professor Hugo Theorell, Medicinska Nobelinstitutet, Biokemiska Avdelningen, to LP RE: Attaches paper sent to Nature, which used the peptide model that LP gave them. Finds it interesting that for a peptide chain which is restricted by not less than three covalent bonds to a rigid structure like the hemin, certain rather definite conclusions concerning the hydrogen bond structure can be made without the aid of x-ray crystallography. Wonders if and where LP has published his new peptide model. Would like to make a quotation in the paper for Acta Chemica Scandinavica. Wonders if LP intends to travel to Europe this summer so that Theorell can see him. [Letter from LP to Theorell July 25, 1955] [Filed under LP Correspondence: (T: Individual Correspondence.
