Klaus H.Schmidt,* Myran C.Sauer, Jr., Yuelie Lu, and Andong Liu: Quantum Yields of Photoionization in the Two-Photon Ionization of Solutes in Hydrocarbon Solutions and Their Relationship to the Observed Conductivity Signal. Page 246, last paragraph, and continuation on page 247. Errors discovered in the computer programs used for calculating the quantum yields for the ionization of the lowest excited singlet and the laser intensity profiles require the following corrections: Page 248, Table 111. The quantum yields, qhA-c. in the rightmost column must be divided by 4. Therefore, the conclusion based on these values (see second paragraph on the same page), namely, that an exponential distribution can be ruled out in the case of isooctane, is invalid. Page 249, Figures 6 and 7. The abscissa values for the laser intensity must be multiplied by 2/3. Note that the relationship between the data points and the calculated curves is not affected. Page 25 1, Summary, last paragraph. Our results do not allow us to rule out any distribution function in the case of photoionization. We would like to acknowledge the collaboration of Martin G. Bakker in analyzing and correcting the computer errors.
