The 298 K Raman and reflection spectra of the polydiacetylene THD, a close structural variant of DCHD, are presented. The polymer double-and triple-bond stretch frequencies are 1485 and 21 I 1 cm-', respectively, and the lowest electronic transition peaks at 17600 cm-'. The reflection spectrum is mo

โฆ Synopsis
Analysis of vibronic structure in the 300 K piezomodulated reflection (PMR) spectra of DCHD and THD indicates the presence of a single allowed electronic state accompanied by significant hot band activity. Observed vibronic progressions and hot bands are consistent with corresponding Raman spectra. The PMR spectra display an enhanced response to the hot bands.

The phase transition in fully polymerized crystals of 2,4-hexadiyne-1,6-diol-bis(ptoluene sulfonate) has been studied using piezomodulated reflection spectroscopy. Temperature dependent spectra show the exciton origin and 1470 cm-' sideband to split first. The energy difference between the exciton o
The 298 K Raman and reflection spectra of a single crystal TCDU polydiacetylene polymorph (TCDU-A') are presented. The lowest energy reflection maximum in TCDU-A\* is seen at 15900 cm-'. Raman and reflection spectra ofTCDU-A\* are similar to those for TCDU-A and thin film TCDU samples and significan
Transient reflectance changes in a polydiacetylene-toluene-sulfonate (PDA-TS) single crystal were found to be induced by pulsed excitations at 2.33 eV (532 nm), 3.49 eV (355 nm), and 4.66 eV (266 nm). The negative reflectance change around 1.4 eV, observed only by excitations at 4.66 and 3.49 eV was
The Raman scattering of MOO, at 300 and 77 K and the infrared reflectivity spectra of MOO, at 300 K have been investigated in different scattering geometries. The Raman spectra of PbMoO, crystals at 77 K have been investigated also. The reflectivity spectra of MOO, crystals were calculated for E 11
