Arcsecond-resolution spectral observations toward the protobinary system IRAS16293-2422 at 344 and 354 GHz were conducted using the Submillimeter Array.Complex organic molecules such as CH3OH and HCOOCH3 were detected. Togetherwith the rich organic inventory revealed, it clearly indicates the existence oftwo, rather than one, compact hot molecular cores (smaller than or equal to 400AU in radius) associated with each of the protobinary components identified bytheir dust continuum emission in the inner star-forming core.Comment: 11 pages, 3 figures, to be published in ApJ
