They consist of a high-sensitivity unbiased spectral survey at the 1mm, 2mm, and 3mm IRAM bands. We detected five iCOMs: acetaldehyde (CH<SUB>3</SUB>CHO), methyl formate (HCOOCH<SUB>3</SUB>), dimethyl ether (CH<SUB>3</SUB>OCH<SUB>3</SUB>), ethanol (CH<SUB>3</SUB>CH<SUB>2</SUB>OH), and formamide (NH<SUB>2</SUB>CHO). In addition, we searched for other iCOMs and ketene (H<SUB>2</SUB>CCO), formic acid (HCOOH) and methoxy (CH<SUB>3</SUB>O), whose only ketene was detected. The numerous detected lines, from 5 to 37 depending on the species, cover a large upper level energy range, between 15 and 254 K. This allowed us to carry out a rotational diagram analysis and derive rotational temperatures between 35 and 110 K, and column densities between 3 × 10<SUP>15</SUP> and 1 × 10<SUP>17</SUP> cm<SUP>-2</SUP> on the 0.3 arcsec size previously determined by interferometric observations of glycolaldehyde. These new observations clearly demonstrate the presence of a rich chemistry in the hot corino towards SVS13-A. The measured iCOMs abundances were compared to other Class 0 and I hot corinos, as well as comets, previously published in the literature. We find evidence that (i) SVS13-A is as chemically rich as younger Class 0 protostars, and (ii) the iCOMs relative abundances do not substantially evolve during the protostellar phase.STAMPAenArticle10.1093/mnras/sty29152-s2.0-85063207926000462258200032https://academic.oup.com/mnras/article/483/2/1850/5174973https://arxiv.org/pdf/1810.11411.pdf2019MNRAS.483.1850BFIS/05 - ASTRONOMIA E ASTROFISICA
