Introduction Recently, there have been a few notable trials to deepen the
fundamental understanding of near infrared (NIR) spectra. One of them is to
apply generalized two-dimensional (2D) correlation spectroscopy to NIR region.1
The basic concept of generating 2D infrared (IR) spectra from perturbation-
induced time-dependent fluctuation of IR signals was introduced by Noda in
1986.2 In 1993, he proposed more generalized 2D correlation spectroscopy to
produce 2D correlation ...

... NMR and other resonance spectroscopy methods, lately a very different form of
2D spectroscopy applicable to many other types of spectroscopic techniques is
also emerging. This book's focus is on this latter type of 2D spectroscopy. The
introduction of the concept of 2D spectroscopy to optical spectroscopy, such as IR
and Raman, occurred much later than NMR in a very different form. The basic
concept of perturbation-based two-dimensional spectroscopy applicable to
infrared (2D ...

Particular emphasis is put on progress in the theory and calculation methods in
2D correlation spectroscopy. A historical review of 2D correlation spectroscopy is
described first, and the mathematical treatment of generalized 2D correlation
spectroscopy is explained next. Then a recently proposed efficient route to
calculating 2D ... The basic concept of 2D infrared (IR) spectroscopy was
proposed by Noda in 1986. 5-7 The conceptual influence of 2D NMR on the early
stage of 2D IR ...

7.5.4 Two-dimensional Infrared Spectroscopy The concept of two-dimensional
infrared spectroscopy (2D IR) was proposed by Noda et al. [10-12]. The
development of 2D IR originates from 2D NMR (the COSY ... The principle of 2D
IR Because the time scale for IR is in the range of 10"12-1(T13 s, which is much
shorter than that for NMR, 2D IR spectra have to be produced by using an
alternative appropriate method. Some perturbation is required to excite the
measured molecules.

Two-dimensional infrared (2D IR) correlation spectroscopy [1-8] is a relatively
new addition to the spectroscopic methods used for the characterization of
polymers. In 2D IR, infrared spectral intensity is obtained as a ... of studies of
polymeric materials by 2D NMR [17-19]. However, until now the propagation of
this powerful concept of multidimensional spectroscopy in other areas of
spectroscopy, especially vibrational spectroscopies such as IR and Raman, has
been surprisingly slow.

The idea of 2D spectroscopy was put forward in NMR spectroscopy, where by
spreading spectral peaks over a second dimension, the visualization of complex
spectra consisting of many overlapped peaks could be simplified. Lately, different
forms of 2D spectroscopy applicable to many other types of spectroscopic
techniques have been developed. The concept of perturbation-based 2D
spectroscopy was introduced by Noda in 1986 (for a review see Noda et al. 2000
).
