+ | Isadore B. Berlman was born in St. Louis MO. USA, January 13, 1922. Berlman completed his A.B. degree in Meteorology at NYU through the US Army. He served 3<math>\tfrac{1}{2}</math> years in the US Air Force as a Meteorologist (1943-1946). He completed his MA in Physics(1946-1948) and his Ph.D. in Nuclear Physics (1948-1950) both at Washington University, St. Louis MO. | ||

My final comment is the most difficult. It concerns my second book, “Energy Transfer Parameters of Aromatic Compounds” Academic Press 1973. There is a high probability that the data is faulty. My problem now arises from the fact that as I am 95 years old and my memory is failing. Examples of memory loss have been as follows: recently some-one sent me the following reprint [5]. | My final comment is the most difficult.

− | Regarding the book, I believe that results there may be wrong. My memory tells me that around 1970-73 I was interested in finding a formula that gives a value for the transfer distance between 2 molecules where the absorption spectrum of one of them overlaps the emission spectrum of the second one. I seem to remember such a formula appeared in an article written by J. Birks ([[Birks John Betteley]]) and someone else. To my chagrin when I examined the formula more closely, I concluded that it was faulty. Therefore, I decided to wait until they published a correction but I have not seen such a correction. Forgetting this I went ahead and used this formula. Years later I realized my mistake but did not know how to correct this. Moreover, I was surprised to learn that I had not referenced this article. I tried to find the original article on the internet but to no avail. On the other hand | + | Regarding the book, I believe that results there may be wrong.

Berlman) which I apparently used, it looks like a standard formula found in many articles on energy transfer. If there is nothing wrong with this formula, the data in the book should be correct. At my age, I am not in the position to verify this. |
Finally, if the data is incorrect and has caused any harm, I apologize. | Finally, if the data is incorrect and has caused any harm, I apologize. | ||
