Abstract: One would expect C2H5-X-H to belong to point group Cs, if C2H5-X-H has the highest symmetry. The number, species and activity of the fundamentals of C2H5-X-H on the assumption of the Cs structure is 13A′(R, p; IR)+8A"(R; IR). However the obtained spectra of C2H5-X-H can never be explained on the basis of Cs selection rules, but can be assigned on the basis of C3v symmetry, in which CH2 group rotates freely with respect to the three H atoms of CH3 group. The irreducible representions of C3v symmetry for CH3-Y-X-H (Y=CH2) is 5A1(R, p; IR) + 5E(R; IR). In addition to these, a few fundamentals should appear due to CH2 group. The non-rigid structure with rotating CH2 group is strongly supported by the NMR spectrum.
