THE HNC/HCN RATIO IN STAR-FORMING REGIONS
THE HNC/HCN RATIO IN STAR-FORMING REGIONS
HNC and HCN, typically used as dense gas tracers in molecular clouds, are a pair of isomers that have great potential as a temperature probe because of temperature dependent, isomer-specific formation and destruction pathways. Previous observations of the HNC/HCN abundance ratio show that the ratio decreases with increasing temperature, something …
