1. Determine the center of mass coordinates for formaldyde, H2C=0. Start with a planar structure with C as the origin. The HCH angle is 120 degrees. The C-0 bond length 1.2 A, the C-H bond length is 1.0 A.
2. Calculate the rotational constants: A, B and C in MHz. Use A (MHz) = 505379 MHz amu A2/ la (amu A2).
3. Determine three transitions from the energy level handout and compare to the JPL database. Determine the percent error of the three transitions.
4. The NIST bond length webpage gives the average C-H length as 1.068 A and a minimum C=0 bond length as 1.11 A. How does that affect the highest frequency transition from problem 3?
Why is there a difference between the conduction of glacial acetic acid (CH3COOH) and 0.1 M Acetic acid (CH3COOH)? Please explain in detail.
The ozone layer is about 20 km thick, has an average total pressureof 10 mm Hg(1.3 * 10^-2 atm ) , and has an average temperature of 230 K. The partial pressure of ozone in the layer is only about 1.2 * 10^-6 mm Hg( 1.6 * 10^-9 atm ).
What are the molecular weights of ether and dimethylether? Are they isomers of each other or is each an isomer of something else? Why are there significant differences in their chemical and physical properties?
