interesting to note that two peaks are present in the spectrum of (3–2) line toward the offset (-10,10), as shown in Fig. \[n2h+32\]. The hyperfine structure (hfs) fit to the (3–2) line, assuming the presence of two velocity components along the line of sight, gives $V_{\rm LSR \, 1}$ = 6.35$\pm$0.1  and $V_{\rm LSR \, 2}$ = 6.55$\pm$0.04 . The line widths of the two components are $\Delta v_1$ = 0.15$\pm$0.02 and $\Delta v_2$ = 0.19$\pm$0.06 , marginally (factor $\la$ 1.5) broader than the thermal  line width at 10 K. Although this result should be confirmed with higher sensitivity data, the velocities are consistent with those of the N1 and N2 () clumps observed by Shinnaga et al. ([@sol03]) with interferometric observations. The hfs fit to the (1–0) line, assuming two velocity components and fixing the velocities to the values found with the (3–2) line, is consistent with the observed spectrum (if the two velocities are not fixed, the hfs fitting procedure applied to the (1–0) spectrum does not converge, probably because the two components are not well separated). This suggests that the two clumps observed by Shinnaga et al. ([@sol03]) in (1–0) are also present in our single dish
