Ogburn, Joyce L. | Acquiring minds want to know: cloth - paper-still, an issue | Acquiring Minds Want to Know column: "In the last issue of Against the Grain, I presented some ideas about the possible assumptions about obligations that underlie the scholarly paperback market. This article gets a little more practical and presents some figures from Yale for your consideration." | Books, paperback; Books, hardback; Acquisitions, libraries | 1994-11 |

Vardeny, Zeev Valentine | Excitons in poly(para-phenylenevinylene) | We show that one-electron band theory fails to describe optical absorption in PPV and the absorption spectrum can be described only within a Coulomb-correlated model. The lowest optical state is an exciton, whose binding energy is estimated theoretically to be 0.90 ± 0 . 1 5 e V Measurements of the... | Poly(para-phenylenevinylene); PPV | 1994-11 |

Vardeny, Zeev Valentine | Transient spectroscopy of excitons and polarons in C60 films from femtosecond to milliseconds | We have studied photoexcitations in C60 films using transient photomodulation and photoluminescence from 100 fs to 50 ms and absorption-detected magnetic resonance (ADMR). We show that singlet Frenkel excitons are the primary photoexcitations; their recombination kinetics in the picosecond time dom... | Transient spectroscopy; C60 films; Femtoseconds; Milliseconds | 1994-11 |
