G35.20 core B shows clear evidence for small-scale chemical segregation. On the left are spectra extracted from each continuum peak in core B (corresponding to the red, blue, and green crosses in the map to the right). It can clearly be seen in the spectra that the N-bearing species (HC3N) is only strong in B3, where the O-bearing species (C2H5OH) is strong in all 3 regions. On the right, the integrated intensity contours of H2CS 101,9–91,8 (0.55, 0.94, 1.34, and 1.73 Jy/beam km s-1), CH3OCHO 279,18–269,17 (0.70, 1.28, 1.85, and 2.43 Jy/beam km s-1), and C2H5CN 401,39–391,38 (0.085, 0.100, 0.115, 0.130, and 0.145 Jy/beam km s-1) are shown overlaid on the continuum (grayscale) for core B of G35.20. While the O- and S-bearing organics are distributed across core B, the N-bearing species is only found toward the southwestern part.
