The spectra were obtained with the SPIRE Fourier-transform spectrometer on board the Herschel Space Observatory, and cover wavelengths from 195-670 ìm, a region of the electromagnetic spectrum hitherto difficult to study in detail. The far infrared spectra of these objects are rich and complex, and we measure over 150 lines in each object. Lines due to 18 different species are detected. We determine physical conditions from observations of the rotational lines of several molecules, and present initial large velocity gradient models for AFGL 618. We detect water in AFGL 2688 for the first time, and confirm its presence in AFGL 618 in both ortho and para forms. In addition, we report the detection of the J = 1-0 line of CH+ in NGC 7027. © 2010 ESO. date: 2010-07-16 date_type: published official_url: https://doi.org/10.1051/0004-6361/201014589 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 357655 doi: 10.1051/0004-6361/201014589 lyricists_name: Barlow, Michael lyricists_name: Matsuura, Mikako lyricists_name: Savini, Giorgio lyricists_name: Swinyard, Bruce lyricists_name: Wesson, Roger lyricists_name: Witherick, Dugan lyricists_name: Yates, Jeremy lyricists_id: MJBAR75 lyricists_id: MMATS97 lyricists_id: GSAVI26 lyricists_id: BSWIN93 lyricists_id: RWESS64 lyricists_id: DWITH96 lyricists_id: JAYAT84 actors_name: Barlow, Michael actors_id: MJBAR75 actors_role: owner full_text_status: public publication: Astronomy and Astrophysics volume: 518 article_number: L144 issn: 1432-0746 citation: Wesson, R; Cernicharo, J; Barlow, MJ; Matsuura, M; Decin, L; Groenewegen, MAT; Polehampton, ET; ...
