    Cytochrome-C Comparison Brief Description: The molecular clock refers to mutations in DNA nucleotide sequence of genes occurring at a constant rate over time. The greater the difference in nucleotide sequence between two individuals of different species‚ the greater the amount of time has passed since they diverged from a common ancestor. The molecular clock helps to provide evidence to support conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis

    medicine. It used to evaluate the kidney stone diseases thus broadening the use of IR in different ways. The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting point work the best together. According to Pub Med the FT-IR spectroscopy can be used to identify bacteria‚ to characterize neoplastic changes

    Nicole Kehler Introduction In the last two decades the literature concerning interorganizational relationships (IRs)‚ particularly strategic alliances‚ joint ventures‚ and social network analysis‚ has exploded. There has been a growing interest in how learning occurs in these various forms of cooperative arrangements. The nascent literature concerning learning processes in IRs suggests that learning occurs on both micro and macro levels (e.g. Knight 2002). At the micro level of analysis‚ inter-personal

    C and the IR spectra displayed a carbonyl peak at 3415 cm-1 ‚‚which represents and OH functional group. The second step of the reaction was to oxidize benzoin to form benzil; this reaction yielded 27.04% benzil. The MP of the benzil was 91O-93O C and the IR spectra revealed no OH functional groups. The last step of the synthesis was a double aldol condensation reaction to form tetraphenylcyclopentadienone; this reaction had a yield of 76.56% and a melting point of 222O-225O C. The IR spectra revealed

    Discussion In this laboratory assignment‚ the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data‚ specifically 1H-NMR‚ 13C-NMR‚ and IR spectroscopy. Although mass spectrometry was given for the samples as well‚ its use was suggested only for confirmation‚ not identification‚ of the unknowns. Mass spectrometry was not included in the identification analysis of the compounds‚ however
