Images of neutral hydrogen (color) and CO J = 1-0 emission (contours) in NGC 3627. The contour levels are 0.04, 0.07 0.11 0.15 0.18 0.22 K in a velocity width of 550 km/s, trace the molecular bar and the dense molecular clouds at the inner Lindblad resonance. The H I level ranges from 0.06 (darker) to 0.37 K (lighter) in a 620 km/s interval, and peaks in a ring at the radius of the inner Lindblad resonance.
