Aldrich Raman Library Listing – 14,033 spectra This library represents the most comprehensive collection of FT-Raman spectral references available. It contains many common chemicals found in the Aldrich Handbook of Fine Chemicals. To create the Aldrich Raman Condensed Phase Library, 14,033 compounds found in the Aldrich Collection of FT-IR Spectra Edition II Library were excited with an Nd:YVO4 laser (1064 nm) using laser powers between 400 - 600 mW, measured at the sample. A Thermo FT-Raman spectrometer (with a Ge detector) was used to collect the Raman spectra. The spectra were saved in Raman Shift format.

New L-serine derivative ligands were prepared and tested as cocatalyst in the Diels-Alder reactions between cyclopentadiene (CPD) and methyl acrylate, in the presence of several Lewis acids. The catalytic potential of the in situ formed complexes was evaluated based on the reaction yield. Bidentate serine ligands showed good ability to coordinate medium strength Lewis acids, thus boosting their catalytic activity. The synthesis of the L-serine ligands proved to be highly efficient and straightforward. 1. Introduction derivative ligands, as alternative to the usual strong Lewis acids. -

Bromodeoxyuridine-Induced Mutations in Synchronous Chinese Hamster Cells: Temporal Induction of 6-Thioguanine and Ouabain Resistance During Dna Replication
BROMODEOXYURIDINE-INDUCED MUTATIONS IN SYNCHRONOUS CHINESE HAMSTER CELLS: TEMPORAL INDUCTION OF 6-THIOGUANINE AND OUABAIN RESISTANCE DURING DNA REPLICATION H. JOHN BURKP AND PAUL M. AEBERSOLD2 Group in Structural Biophysics, Biomedical Diuision, Lawrence Berkeley Laboratory', and Dept. of Molecular Biology2, Uniuersity of California, Berkeley, California 94720 Manuscript received November 14, 1977 Revised copy received April 25, 1978 ABSTRACT Mutations were induced in synchronous Chinese hamster cells by bromo- deoxyuridine (BUdR) incorporated into cells for one-hour periods in the cell cycle. There was a very pronounced temporal dependence during the first half of the DNA synthesis period for th:! induction of damage leading to 6-thio- guanine (6TG) and ouabain resistance. No mutants above background were induced by exposure to BUdR in GI and G2 cells, and very few mutants were induced in the latter part of the DNA synthesis period. The peak for the induction of 6TG resistance occurs at about two hr in the DNA synthesis period; one hour later there is a peak for the induction of ouabain resistance. Both peaks occur before the time of maximum incorporation of BUdR into DNA. These results suggest that the mutagenesis by BUdR is associated with at least two nuclear genes, which replicate at two hr and three hr in the DNA synthesis period. AMMALIAN cells replicate their several meters of DNA under culture Mconditions in about six to eight hr. Replicating units of the DNA replicate in two directions at a rate of about 1 micron per minute (HUBERMANand RIGGS 1968). The number of replicating units replicating during any one minute of the DNA synthesis period is on the average about lo4 (PAINTERand SCHAFER1969; PAINTER,JERMANY and RASMUSSEN1966). -
