Predicted spectroscopic constants (in MHz) for isotopic species of CH₃C₃N and CH₃C₄H.

Species	B
¹³CH₃CCCN	2010.51
CHCCCN	2054.75
CH₃C¹³CCN	2065.71
CH₃CC¹³CN	2048.72
CH₃CCC¹⁵N	2011.56

¹³CH₃CCCCH	1982.60
CHCCCCH	2025.34
CH₃C¹³CCCH	2035.71 ^(b)
CH₃CC¹³CCH	2018.90
CH₃CCC¹³CH	1980.28

CH₂DCCCCH ^(a)	A = 120899.40
	B = 1965.96
	C = 1958.41

Notes. For all the ¹³C and ¹⁵N species the A value can be assumed for the corresponding parent species, CH₃C₃N or CH₃C₄H, 158 099.0 and 159 140.0 MHz, respectively.

^(a)

A, B, and C constants are provided due to the C_s symmetry of this species.

^(b)

For this isotopologue laboratory data are available (Cazzoli et al. 2008). The experimental rotational constant B is 2035.67752 MHz.
