Plagiarism is commonly defined as representing as one’s own the ideas and/or writing of another. This includes using another author’s sentences or paragraphs, or significant portions thereof, without quotation marks and an appropriate citation, and conveying information that is not commonly known without citing the authors whose original discovery or insight that information represents.

Suppose a physics student reads the following from a published paper while preparing an essay:

"On the basis of the infrared spectra of the adenine molecule in the gas phase, in an argon matrix, and from theoretical calculations, it is found that the free adenine molecule is almost planar with the strongest vibrational mode at 1629 cm^-1, assigned to the NH₂ scissoring mode and frequently found to be intense in many molecules containing the NH₂ group. The low intensity of this mode for adenine on Cu(110) indicates either the NH₂ group has dissociated or the NH₂ group is almost parallel to the substrate. Our temperature-programmed desorption studies show that there is no desorption associated with the dissociation of the NH₂ below 430 K, the annealing temperature. Thus we can conclude that the NH₂ plane is close to parallel to the substrate, while the C- NH₂ bond is tilted away from this plane." Chen, Q., Frankel, D., and Richardson, N. "Self-Assembly of Adenine on Cu(110) Surfaces," Langmuir 18, 3219 (2002).

On the following pages, you will be asked to determine, based on the source shown above, whether a passage included in a student essay would constitute plagiarism.
