Amixture of two compounds (a and b) was separated by gas chromatography on a non-polar column. the first peak on the chromatogram corresponds to compound a, and that peak was observed at a distance of 5.42 cm from the sample injection point, and it had a height of 3.59 cm and a width at half-height of 1.88 cm. the peak corresponding to b was observed at a distance of 8.99 cm from the injection point, and it had a height of 3.55 cm and a width at half-height of 1.54 cm. the chart paper speed used in the experiment was 100. mm per minute. what was the retention time for compound a (in seconds)?

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
