This is true even if conformations are sampled at rapid (nanosecond or picosecond) rates. The time-dependent behavior of magnetization becomes important when considering nanoscale and nanosecond timescale magnetization. Thus ISRS cannot be observed using nanosecond pulses making ordinary time-incoherent light. High peak power and nanosecond pulses improve marking and engraving. Spin lifetimes of conduction electrons in metals are relatively short (typically less than 1 nanosecond). Many metallated paramagnetic texaphyrin species exhibit triplet-state lifetimes in the nanosecond range. Dynistors can be used as switches in micro- and nanosecond power pulse generators. Subsequent experiments demonstrated that fission took less than a nanosecond too. They calculated that most were emitted in less than 1 nanosecond. One proposed method for detecting shielded Dirty Bombs is Nanosecond Neutron Analysis (NNA). Those holes evaporated via Hawking radiation in a nanosecond. The devices can be switched on and off at the nanosecond time scale. This causes the reactions to occur extremely quickly (~1 nanosecond).
