Results are presented from the first cometary observations using the Atacama Large Millimeter/Submillimeter Array (ALMA), including measurements of the spatially resolved distributions of HCN, HNC, H2CO, and dust within the comae of two comets: C/2012 F6 (Lemmon) and C/2012 S1 (ISON), observed at heliocentric distances of 1.5 AU and 0.54 AU, respectively. These observations (with angular resolution ≈0.″5), reveal an unprecedented level of detail in the distributions of these fundamental…

Sublimation from icy jets as a probe of the interstellar volatile content of comets
TLDR
High-resolution observations of emission from the molecules HNC, DCN and HDO associated with comet Hale–Bopp reveal arc-like structures—icy jets—offset from (but close to) the nucleus, and suggest that, by mass, Hale-Bopp (and by inference the outer regions of the early solar nebula) consists of largely unprocessed interstellar material.

Origin of the formaldehyde (H2CO) extended source in comet C/1995 O1 (Hale-Bopp)
Chemical processing in the coma as the source of cometary HNC
TLDR
It is shown that the HNC/HCN ratio determined for comet Hale–Bopp varied with heliocentric distance in a way that matches the predictions of models of gas-phase chemical production of HNC in the coma, but cannot be explained if the H NC molecules were coming from the comet's nucleus.
