Small signal gain and vibrational relaxation for (13)CO(2)
Abstract:
We have determined the small signal gain for the P(18) transition of the (13)CO(2) and (12)CO(2) isotopes for identical pumping conditions in an x-ray preionized discharge amplifier. We have also determined vibrational-relaxation rate constants for He, N(2), and (13)CO(2) from the decay of the small signal gain on the P(18) transition of (13)CO(2) in the same x-ray preionized discharge amplifier. The vibrational-relaxation rate constants for N(2) and (13)CO(2) on the (13)CO(2)P(18) transition at 11.1 microm are a factor of 3 faster than the corresponding rate constants for the (12)CO(2) isotope.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
¹H NMR: Interpreting Distorted and Overlapping Signals
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
