K.D.Kreutter, J. M.Nicovich, and P.H.Wine*: Kinetics and
Thermochemistry of the Br(ZP31z)+ NO2 Association Reaction.
Pages 4020-4028. In this paper we determined U P B 8for the title reaction to be -19.6 f 1.7 kcal mol-l. By combining the measured with known heats of formation for Br(2P,,z) and NOz, we obtained a value for the heat of formation (AHfOm8) of BrN02. Due to an arithmetic error which went undetected, AHf0z98(BrN0z) was incorrectly reported to be 17.0 f 1.8 kcal mol-l; the correct value is AHfozs8(BrNOz)= 15.0 f 1.8 kcal mor1. The incorrect heat of formation appears in the abstract (page 4020), in the main body of the text (page 4025), and in the summary (page 4028).

In the second column, third line of the Introduction, the correct word is ”protons”, not “photons”.

The correct equation is as follows I,
pi = ,,,,CiAi/C,,CrA‘ r-0

where . C, is the binomial coefficient, and A is the probability factor that a binding site is occupied by Niz+;in this case the mean number of bound Ni2+per micelle, ( i ) , is related to A as (i) = AZ,,,/(l + A). Since the actual calculation was executed with the correct equation, there is no problem on the conclusions. I thank Dr. Masanori Tachiya for bringing this error to my attention.

Equation 1 should appear as follows: r ( - ) = ylo(3 cos2 e + 1) The value of 13 f 9O that appears in the Abstract and in the Discussion for the angle Oa8 between the transition moments of the a84 and j384 chromophores in the a@ monomer in allophycocyanin is recalculated using the above formula to be 20 f 9O.
