Isotopes can be used as markers to keep track of positions of atoms during a chemical transformation. This strategy of determining reaction mechanisms is illustrated in the article with several examples. 相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing
with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences
and viewpoints on matters related to teaching and learning science. 相似文献

A novel way to isolate the highly reactive cyclobutadiene molecule is by trapping it inside a much larger molecule. 相似文献

Motion of a tiny tool thrown by an astronaut inside a spinning space vehicle in a state of free fall
S N Maitra 《Resonance》2007,12(4):80-84
One of two astronauts, while conducting an experiment inside a spinning space vehicle in a state of free fall neglecting all
gravitational effects, throws a tiny tool at the other with a velocity perpendicular to its axis of rotation. Considering
the motion of the tool with respect to the rotating frame rigidly fixed to the vehicle, we can obtain the position of the
tool at a subsequent time by use of rotational kinematics and geometry without involving the concepts of coriolis and centripetal
forces. 相似文献
