Notes. Species marked with a star (★) are newly added formation enthalpies for deuterated isotopologues. If not stated otherwise the formation enthalpies are adopted from Du et al. (2012). The values marked with a are adopted from the NIST Chemistry WebBook(1) and the ones marked with b are from the Kinetic Database for Astrochemistry(2). The binding energies are taken from Semenov et al. (2010). (1)https://webbook.nist.gov/chemistry (2)https://kida.astrochem-tools.org
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
