bottleneck (bÅt'l-nÄk') An abrupt and severe reduction in the number of individuals during the history of a species, resulting in the loss of diversity from the gene pool. The generations following the bottleneck are more genetically homogenous than would otherwise be expected. Bottlenecks often occur in consequence of a catastrophic event.
Nuclear Overhauser Effect. The Nuclear Overhauser Effect or NOE is the enhancement of one spin's signal due to magnetisation transfer via cross relaxation in a dipolar coupled spin system. In the steady state NOE one transition between two spins in an AX system is selectively saturated by an rf-pulse.
