Assign functional groups/vibrations (bending, stretching) to each peak for the computational IR spectrum for carbon dioxide shown below. From left to right the peak numbers are 1485 cm^-1, 864.5 cm^-1, and 644 cm^-1. . 40 Transmittar 3000 1000 2000 Wavenumber (cm-1)
Identify the important diagnostic peaks from the IR spectrum, including the cm^-1, and the bond that corresponds to each peak. List all possible classes of compounds this compound could be. Does it contain carbon-carbon double or triple bonds? From the mass spectrum and IR, determine the molecular formula and calculate the degree of unsaturation. On the basis of your analysis, propose a structure that fits all the IR, MS, & CNMR data. Propose a structure that corresponds to the base...
This question is about inorganic Chemistry regarding CO stretching and Group Theory. Cobalt tetracarbonyl hydride, HCo(CO)_4, is an important industrial catalyst for the production of aldehydes from alkenes, carbon monoxide, and hydrogen gas via a process called hydroformylation. The compound is a low boiling liquid, which makes structural characterization difficult. Two possible structures are shown below. Predict the number of CO stretching frequencies expected in the IR and Raman spectrum for both structures. Which structure is the correct structure based...
