Bonding mode assignment
There are a number of ways you can approach the assignment of the bonding mode.
However, the data sometime are sufficiently complex that the students initially often reach
wrong conclusion by over emphasizing one piece of data, that is, the C-N stretching frequency.
As can be seen in Table 2, for instance, the Mn unknown C-N stretching frequency is actually
closet to that of KSCN reference (ionic bonding). However, the C-S stretching frequency is also
considered, the closet match is to that of the Co reference (M-NCS bonding). Therefore, in this
experiment we will use a more quantitative comparison method where the absolute differences
